Hydraulic Cylinder Honing vs Skiving: Which Bore Finishing Method Is Better?<\/h2>\n

A manufacturer’s guide to bore surface quality, tolerance control, and selecting the right finishing process for demanding hydraulic applications across UK industry.<\/p>\n<\/div>\n

\"EverWhen a hydraulic cylinder fails in service \u2014 whether in a Sheffield steel plant, a Birmingham construction equipment yard, or an offshore platform off Aberdeen \u2014 the root cause more often than not traces back to the bore surface. The inner tube wall is where the seal rides, where friction is generated, and where contamination particles either pass harmlessly or embed and score. Getting that surface right demands a deliberate choice between two proven machining processes: honing and skiving. Both produce a smooth, geometrically accurate bore, but they differ fundamentally in the way metal is removed, the surface texture they leave behind, and the type of application each serves best. Understanding these differences is not a matter of factory trivia \u2014 it directly determines seal life, cylinder cycle count, leakage rates, and total cost of ownership for any hydraulic system operating under real industrial conditions.<\/p>\n

British hydraulic component buyers, plant engineers, and OEM procurement teams face this choice constantly. Whether specifying cylinders for agricultural machinery in the East Midlands or for heavy earthmoving equipment working on infrastructure projects from Manchester to Cardiff, the bore finishing method embedded in a manufacturer’s process defines the product’s reliability ceiling. This guide cuts through the marketing language and delivers a direct technical comparison so engineers can make the right call.<\/p>\n<\/div>\n

The Core Mechanics: What Each Process Actually Does to the Metal<\/h2>\n
\n

<\/p>\n

\n
Honing<\/div>\n

Honing uses a rotating tool fitted with abrasive sticks \u2014 typically made from aluminium oxide, silicon carbide, or CBN (cubic boron nitride) \u2014 that expands radially against the bore wall while the tool simultaneously reciprocates axially. The combined rotary and linear motion produces the characteristic cross-hatch pattern visible on a correctly honed bore surface. This cross-hatch geometry is not cosmetic; the angular grooves function as micro-reservoirs for lubricating oil film, which is exactly what a reciprocating hydraulic seal needs to survive millions of cycles without dry contact. Honing removes material in very small increments \u2014 typically in the region of 0.01 mm to 0.05 mm per pass \u2014 making it a precision finishing operation rather than a material removal process. It corrects minor geometric deviations such as out-of-roundness and taper left by previous operations like cold drawing or turning, and it achieves bore roughness values (Ra) between 0.2 \u00b5m and 0.8 \u00b5m depending on the abrasive grit and tool pressure selected.<\/p>\n<\/div>\n

<\/p>\n

\n
Skiving + Roller Burnishing<\/div>\n

Skiving \u2014 almost always used in combination with roller burnishing, hence the industry shorthand “skiving-burnishing” \u2014 is a two-stage single-pass operation performed on a specialised machine. In the skiving phase, indexable carbide inserts arranged in a cutting head remove material from the bore wall in a single axial pass, achieving dimensional accuracy and straightness at far higher rates than honing. In the immediately following burnishing phase, hardened steel rollers plastically deform the surface peaks left by the cutting inserts, cold-working the material to achieve a smooth, work-hardened surface with roughness values as low as Ra 0.05 \u00b5m to 0.2 \u00b5m. The plastically deformed surface layer has higher hardness and compressive residual stress than the base metal, which translates to better fatigue and wear resistance in service. The entire combined skiving and burnishing operation takes a fraction of the time required to hone a tube of equivalent length.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

<\/p>\n

\n

Surface Texture, Oil Film, and What Seals Actually Need<\/h2>\n

The connection between bore surface finish and seal performance is more nuanced than a single Ra number. Hydraulic seals \u2014 polyurethane U-cups, PTFE buffer seals, composite wiper rings \u2014 function by maintaining a coherent oil film between the seal lip and the bore wall. If the surface is too rough, the peaks abrade the seal material and the valleys trap contaminant particles that score the bore. If the surface is mirror-smooth, the oil film breaks down, the seal runs partially dry, and friction spikes cause stick-slip motion that degrades positional accuracy in servo-controlled circuits.<\/p>\n

\n
\n
Honed Cross-Hatch Pattern<\/div>\n

The 30\u00b0 to 45\u00b0 angle cross-hatch produced by honing is the gold standard for conventional hydraulic seals. The angled channels carry oil under the seal as the piston rod or piston advances and retracts, creating a stable elastohydrodynamic lubrication regime even at slow speeds and high clamping loads. This is why honing remains the preferred bore finishing process for cylinders that run slow-speed, high-load cycles \u2014 such as press cylinders, forging presses, and heavy earthmoving bucket circuits \u2014 where the oil replenishment function of the cross-hatch pattern makes the difference between a 20,000-hour seal life and a 3,000-hour one.<\/p>\n<\/div>\n

\n
Burnished Plateau Surface<\/div>\n

Roller burnishing produces what tribologists call a plateau surface \u2014 a flat, hard running surface interrupted by fine valleys. This geometry suits modern composite and PTFE-backed seals very well, since these materials generate less friction and tolerate a smoother counter-surface without risking dry running. The higher surface hardness from cold-working (typically an increase of HV 50 to HV 150 depending on base material) also slows the rate of bore wear under contaminated fluid conditions. For cylinders running higher-speed duty cycles in mobile hydraulic applications \u2014 like aerial work platforms and telehandlers common on UK construction sites \u2014 the burnished surface often produces lower running temperatures and quieter operation.<\/p>\n<\/div>\n

\n
Cleanliness and Particle Count<\/div>\n

From a contamination control standpoint \u2014 a critical concern for any hydraulic system certified to NAS 1638 or ISO 4406 \u2014 skiving-burnished bores have an advantage in part because the process generates fewer loose abrasive particles. Honing produces fine aluminium oxide or silicon carbide swarf that must be thoroughly flushed before assembly. If residual abrasive remains in a honed bore and enters the hydraulic circuit, it acts as a lapping compound and accelerates wear across the entire system. Rigorous post-honing cleaning protocols are non-negotiable. Skiving produces metal chips that are easier to remove with a single air blast and wipe, though both processes require proper cleanliness validation before final assembly.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Industrial Application Scenarios and Which Method to Specify<\/h2>\n

<\/p>\n

\n
\n
Aerial Work Platform Application<\/div>\n

\"EverAerial work platforms represent one of the most demanding environments for hydraulic cylinder bore quality. The cylinders extend and retract thousands of times per year, often in outdoor environments where temperature swings and contaminated air accelerate wear. The boom angle cylinders used on folding boom AWPs require dimensional accuracy over their full stroke to maintain the precise articulation angles needed for safe working at height. For this application, skiving-burnished bores offer production efficiency at scale and the surface hardness that resists abrasive wear from externally contaminated fluid. Our Klappbarer Auslegerwinkelzylinder (1458 mm Hub)<\/a> is produced to this standard, with bore tolerances and surface specifications set to meet the duty cycle demands of OEM aerial platform manufacturers supplying the UK construction and utilities sectors.<\/p>\n

Similarly, the main boom circuit in a telescopic aerial platform requires a cylinder that can maintain position precisely at full extension. Our Aerial Platform Main Boom Angle Cylinder (555mm Stroke)<\/a> uses a bore finished and verified to tight surface roughness limits, ensuring the seal package performs reliably throughout its service life on both urban utility work and building maintenance applications common from London Docklands to the new developments in Leeds and Birmingham’s Digbeth quarter.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n
\n
\n
Hydraulic Presses \u2014 Sheffield Forgemasters & Heavy Fabrication<\/div>\n<\/div>\n
\n

Forging presses and press-brake hydraulic cylinders in Sheffield’s remaining heavy engineering sector operate at extremely slow stroke velocities \u2014 sometimes less than 5 mm\/s \u2014 under pressures of 350 bar and above. At these conditions, the cross-hatch pattern produced by honing is essential: it maintains an oil film under conditions where fluid-film lubrication would otherwise break down entirely. Honed bores of 150 mm to 400 mm diameter with surface roughness in the Ra 0.4 \u00b5m to 0.6 \u00b5m range consistently outlast burnished bores in this specific duty. The geometric correction capability of multi-stroke honing also addresses the inevitable deflection that occurs when welding heavy end caps onto large-diameter tube sections, making it indispensable for large custom-built press cylinders.<\/p>\n<\/div>\n<\/div>\n

\n
\n
Mobile Construction Equipment \u2014 OEM Series Production in Midlands<\/div>\n<\/div>\n
\n

The midlands manufacturing belt \u2014 JCB’s Staffordshire facilities, the Terex and Liebherr supply chains around Birmingham \u2014 demands high-volume cylinder production where consistency and throughput are as important as peak performance. Skiving-burnishing suits this environment well. A skiving-burnished 80 mm bore tube can be processed in under two minutes, against up to fifteen minutes for a comparable honed bore. When you multiply that across thousands of lift arm cylinders, tilt cylinders, and crowd cylinders per month, the production advantage is significant. The burnished surface also provides excellent compatibility with the polyurethane and PTFE compound seals increasingly used by OEM seal designers, providing quieter operation and more consistent break-out forces across a production batch \u2014 a key quality metric for OEM acceptance testing.<\/p>\n<\/div>\n<\/div>\n

\n
\n
Agricultural Machinery \u2014 Combine Harvesters and Telescopic Handlers<\/div>\n<\/div>\n
\n

The seasonal intensity of UK agriculture \u2014 compressed harvest windows in the East Anglia grain belt and the West Country’s varied crop calendar \u2014 puts severe demands on hydraulic systems in combine harvesters, self-propelled crop sprayers, and telehandlers. These machines need hydraulic cylinders that perform reliably in dusty, high-vibration environments and tolerate occasional contamination ingress without catastrophic failure. For the majority of agricultural cylinder applications \u2014 particularly smaller diameter units from 40 mm to 100 mm bore \u2014 skiving-burnished tubing offers the right blend of throughput, surface quality, and bore hardness. The compressive surface layer provides some resilience against the particulate contamination that is unavoidable in field conditions, even with regular hydraulic fluid changes and filter maintenance.<\/p>\n<\/div>\n<\/div>\n

\n
\n
Marine and Offshore \u2014 North Sea Platform Equipment<\/div>\n<\/div>\n
\n

Hydraulic cylinders deployed on North Sea platforms and in Aberdeen’s offshore supply base face a combination of challenges that makes bore quality especially critical: corrosive salt air, extreme temperature ranges across the annual operating cycle, water-glycol or fire-resistant hydraulic fluids that offer less natural lubrication than standard mineral oil, and inspection intervals that make in-service replacement extremely costly. For these applications, honing is generally preferred \u2014 not only because the cross-hatch pattern works effectively with fire-resistant fluid formulations, but because skilled hone operators can restore a worn bore in a field workshop by bringing it back into specification with a subsequent honing pass, something that is not practically feasible with a skiving-burnished bore. This repairability factor carries real economic weight when a cylinder is 150 metres below the platform deck in a cramped subsea actuator housing.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Materials and Their Influence on Finishing Method Selection<\/h2>\n

The base material of the hydraulic cylinder tube is not a secondary consideration \u2014 it is one of the primary factors that determines whether honing or skiving-burnishing will deliver the best result. The two processes interact with metal in fundamentally different ways, and some tube materials respond far better to one than the other. Understanding this relationship prevents costly process mismatches that degrade bore quality or shorten tube service life.<\/p>\n

\n
\n
Cold-Drawn Seamless Steel (E355 \/ St52)<\/div>\n

The workhorse tube material for hydraulic cylinders worldwide, E355 cold-drawn seamless steel has a consistent yield strength of 355 MPa minimum and a bore surface from the drawing process that already approaches the tolerances needed for skiving-burnishing entry. For standard mobile hydraulic applications, skiving-burnished E355 tube is the most economical and technically sound combination available. The material’s work-hardening rate is predictable, and the rolled burnishing operation consistently achieves surface hardness improvements of HV 60 to HV 100 above the base material specification. Honing is equally applicable where geometric correction after welding or heat treatment is required.<\/p>\n<\/div>\n

\n
Chrome-Molybdenum Alloy Steel (42CrMo4)<\/div>\n

42CrMo4 is selected for high-pressure, thin-wall cylinders where yield strength and fatigue life take priority. Its higher hardness (typically HRC 28 to 36 after heat treatment) makes honing with CBN abrasive sticks the technically preferred finishing route because conventional aluminium oxide stones load rapidly with the harder material. Skiving carbide inserts handle 42CrMo4 well, but the burnishing force required to achieve a satisfactory surface must be carefully calibrated to avoid cracking in the heat-affected zone of welded components. Experienced hydraulic cylinder manufacturers routinely finish 42CrMo4 by both methods but apply tighter in-process monitoring when burnishing heat-treated material.<\/p>\n<\/div>\n

\n
Stainless Steel (316L, 304)<\/div>\n

Stainless steel cylinder tubes, specified for food processing equipment, pharmaceutical plant, marine deck hardware, and chemical process applications, present the most challenging finishing scenario. Austenitic grades like 316L have a strong tendency to work-harden during machining, which can cause cutting tool loading during skiving and unpredictable surface quality during burnishing if cutting speeds and feeds are not precisely controlled. Honing with appropriate abrasive selection and lubricant \u2014 typically a high-pressure sulphurised grinding oil \u2014 provides more process control and more consistent surface finish on stainless bores. For stainless applications across UK food processing facilities in the Yorkshire and Lancashire valleys, honing remains the recommended and most widely specified process.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Customer Success Story: Leeds-Based Mobile Plant Manufacturer<\/h2>\n
Leeds, West Yorkshire \u00b7 Access Equipment Manufacturing<\/div>\n

\"Bohrungsbearbeitung<\/p>\n

A mid-sized OEM based in the Aire Valley industrial corridor near Leeds had been manufacturing articulated boom lifts for the UK construction rental market for over a decade. Their hydraulic cylinder supplier at the time used only a honing process for bore finishing, which delivered acceptable performance on the main boom cylinders but was creating a bottleneck in production scheduling \u2014 honing the cylinder bores across their seasonal peak production run of 60 machines per month was consuming significantly more machine time than their capacity allowed.<\/p>\n

Their design team approached Ever Power after seeing our technical documentation on the skiving-burnishing process. Following a detailed application review \u2014 including load data, expected duty cycles, seal specification, and fluid cleanliness targets \u2014 our engineering team recommended transitioning the 80 mm and 100 mm boom angle cylinder tubes to a skiving-burnished finish while retaining honing for the two large-diameter levelling cylinders where slow-speed operation made the cross-hatch pattern more valuable.<\/p>\n

The hybrid approach \u2014 using both bore finishing methods strategically within the same machine design \u2014 cut the customer’s cylinder lead time by 34% and reduced bore-related seal failures in the first 500 field hours by approximately 60% compared to their previous single-process supplier’s product. Seal break-out force consistency across production batches also improved markedly, allowing the customer to reduce their own factory acceptance test time per machine. The customer has since extended the partnership to cover their new 28-metre all-terrain boom platform product line, with cylinder specifications developed jointly with Ever Power’s application engineering team.<\/p>\n

“We had a bore-related seal failure rate that was genuinely costing us money on warranty claims.

Making the Decision: A Practical Selection Framework<\/h2>\n

The question of honing versus skiving-burnishing rarely has a single correct answer at the application level \u2014 it has a context-dependent correct answer. The selection framework below captures the most important variables that experienced hydraulic engineers use when specifying bore finishing methods. Think of it as a set of questions to work through with your cylinder supplier’s application team rather than a prescriptive rulebook, because real applications almost always involve compound factors.<\/p>\n

H\u00e4ufig gestellte Fragen<\/h2>\n

<\/p>\n

\n
\n
\n
Wie wirkt sich das Honen von Hydraulikzylinderbohrungen tats\u00e4chlich auf die Lebensdauer der Dichtungen von langsamhubigen Pressenzylindern aus, die in einer Schmiedeumgebung in Sheffield betrieben werden?<\/div>\n<\/div>\n
\n

Bei Anwendungen mit langsamen H\u00fcben und hoher Belastung in Pressen dient die durch das Honen erzeugte Kreuzschliffstruktur als Schmierstoffspeichernetzwerk \u00fcber die gesamte Bohrungsoberfl\u00e4che. Da sich die Kolbendichtung mit sehr geringer Geschwindigkeit bewegt \u2013 manchmal unter 5 mm\/s \u2013 ist der hydraulische Druck im Schmierfilm nicht ausreichend, um eine nat\u00fcrliche elastohydrodynamische Schmierung aufrechtzuerhalten. Die Mikrokan\u00e4le im gehonten Kreuzschliffmuster transportieren \u00d6l durch Kapillarwirkung unter die Dichtfl\u00e4che und verhindern so die Grenzschmierung, die Dichtungsmaterialien schnell verschlei\u00dft. In einer Sheffield-Schmiedepresse, die mit 350 bar betrieben wird, erzielt eine korrekt spezifizierte, gehonte Bohrung mit einer Rauheit (Ra) von 0,4 \u00b5m bis 0,6 \u00b5m typischerweise die zwei- bis dreifache Lebensdauer der Dichtung im Vergleich zu einem gleichwertigen Zylinder mit glatter Bohrung im gleichen Betriebszyklus. Temperatur, Reinheit des Schmierstoffs und die Wahl des Dichtungsmaterials beeinflussen die Oberfl\u00e4chenqualit\u00e4t der Bohrung, daher sind diese Werte eher Richtwerte als Garantien. Der Vorteil des Honens bei langsamen H\u00fcben und hoher Belastung wird jedoch in der Fachliteratur und in der Praxis best\u00e4tigt.<\/p>\n<\/div>\n<\/div>\n

\n
\n
Wie gro\u00df ist der typische Preisunterschied zwischen gehonten und gesch\u00e4lten\/polierten Hydraulikzylinderrohren bei einer Bestellung von einem britischen B2B-Lieferanten?<\/div>\n<\/div>\n
\n

Der Preisunterschied h\u00e4ngt ma\u00dfgeblich vom Bohrungsdurchmesser, der Rohrl\u00e4nge, der Werkstoffg\u00fcte und der Bestellmenge ab. Bei der Rohmateriallieferung \u2013 vor der Montage zu fertigen Zylindern \u2013 sind gesch\u00e4lte und polierte Rohre aus Standardwerkstoff E355 mit Bohrungsdurchmessern von 40 mm bis 160 mm preislich vergleichbar mit oder etwas teurer als gehonte Rohre gleicher Spezifikation. Dies liegt daran, dass das Sch\u00e4l- und Polierverfahren zwar schneller ist, aber teurere Anlagen erfordert. Der Kostenvorteil des Sch\u00e4l- und Polierverfahrens pro Einheit macht sich typischerweise erst bei hohen St\u00fcckzahlen bemerkbar, wenn die Maschinenauslastung den Unterschied in den Investitionskosten vernachl\u00e4ssigbar macht. Bei Sonderanfertigungen oder Kleinserien, bei denen das Honen auf einer vorhandenen Honmaschine durchgef\u00fchrt wird, kann das Honen auf der Rohmaterialebene geringf\u00fcgig g\u00fcnstiger sein. Bei komplett kundenspezifisch gefertigten Zylindern ist die Bearbeitungsmethode der Bohrung selten der dominierende Kostenfaktor \u2013 Werkstoff der Komponenten, Chromschichtdicke der Kolbenstange, Dichtungssystem und Geometrie der Endkappe haben einen gr\u00f6\u00dferen Einfluss auf den Gesamtpreis.

Welches Verfahren zur Oberfl\u00e4chenbearbeitung von Zylinderbohrungen sollte ich f\u00fcr Hydraulikzylinder w\u00e4hlen, die auf Hubarbeitsb\u00fchnen auf Baustellen in Birmingham, Gro\u00dfbritannien, eingesetzt werden, und wo kann ich ein Angebot einholen?<\/div>\n<\/div>\n
\n

F\u00fcr Zylinder von Hubarbeitsb\u00fchnen \u2013 insbesondere f\u00fcr Auslegerwinkel- und Jib-Zylinder mit Bohrungsdurchmessern von 50 mm bis 120 mm und mittleren Betriebsgeschwindigkeiten \u2013 ist das W\u00e4lzpolieren in der Regel die bevorzugte Methode. Die h\u00f6here Oberfl\u00e4chenh\u00e4rte durch das W\u00e4lzpolieren bietet eine bessere Best\u00e4ndigkeit gegen das Eindringen von Verunreinigungen, das auf stark frequentierten Baustellen in Birmingham und den West Midlands h\u00e4ufig vorkommt. PTFE-beschichtete Dichtungen, die aufgrund ihrer geringen Reibung und des reibungslosen Selbstnivellierungsvorgangs bei modernen Hubarbeitsb\u00fchnen-Zylinderkonstruktionen Standard sind, harmonieren optimal mit der Plateau-Oberfl\u00e4chenstruktur einer polierten Bohrung. F\u00fcr die Hauptst\u00fctz- und Stabilisierungszylinder derselben Maschine \u2013 die einen gr\u00f6\u00dferen Durchmesser aufweisen und mit sehr niedriger Drehzahl unter hoher Klemmkraft arbeiten \u2013 kann Honen weiterhin die bessere Wahl sein. Ever Power pr\u00fcft gerne Ihre Zylinderzeichnungen und Betriebsdaten und empfiehlt Ihnen das passende Oberfl\u00e4chenbearbeitungsverfahren f\u00fcr jeden Zylinder Ihrer Konstruktion.

Wie kann ich feststellen, ob mein derzeitiger britischer Lieferant von Hydraulikzylindern tats\u00e4chlich eine durch Sch\u00e4len polierte Bohrung verwendet oder lediglich eine gehonte Bohrung mit moderner klingender Terminologie beschreibt?<\/div>\n<\/div>\n
\n

Es gibt mehrere praktische Pr\u00fcfverfahren. Eine fachgerecht gesch\u00e4lte und polierte Bohrung weist unter 10-facher Vergr\u00f6\u00dferung kein sichtbares Kreuzschliffmuster auf \u2013 die Oberfl\u00e4che sollte glatt erscheinen, mit einer leichten linearen Textur vom Sch\u00e4lvorgang, aber ohne schr\u00e4ges Rillennetz. Gemessene Ra-Werte unter 0,2 \u00b5m sind nur durch Polieren, nicht durch Standardhonen, erreichbar. Fragen Sie Ihren Lieferanten nach den spezifischen Ra- und Rz-Werten Ihrer Bohrung sowie nach der Messmethode (die Tastschnittprofilometrie ist Standard). Ein fachgerechtes Sch\u00e4l- und Polierverfahren erzeugt zudem eine h\u00e4rtere Oberfl\u00e4chenschicht \u2013 fordern Sie die Vickers-H\u00e4rte der Oberfl\u00e4che an, wenn Sie eine vollst\u00e4ndige \u00dcberpr\u00fcfung w\u00fcnschen. Kann der Lieferant keine Bohrungsmessberichte mit Ra-Werten und Rundheitsdaten als Standarddokumentation bereitstellen, ist dies allein schon ein Qualit\u00e4tsmangel, der untersucht werden sollte, unabh\u00e4ngig davon, welches Bearbeitungsverfahren er angibt.<\/p>\n<\/div>\n<\/div>\n

Welche Kosteneinsparungen kann ein britischer Landmaschinenhersteller in den East Midlands realistischerweise erwarten, wenn er von gehonten auf gesch\u00e4lte und polierte Zylinderrohre f\u00fcr die Hydraulik von M\u00e4hdreschern umsteigt?<\/div>\n<\/div>\n
\n

Die Kosteneinsparungen durch den Umstieg auf geschliffene Zylinderrohre ergeben sich prim\u00e4r aus k\u00fcrzeren Produktionszeiten, geringeren Ausschussquoten aufgrund von Ma\u00dfabweichungen und \u2013 bei Bezug von einem Hersteller, der die Prozesseffizienz an seine Kunden weitergibt \u2013 einem leicht niedrigeren St\u00fcckpreis bei gr\u00f6\u00dferen St\u00fcckzahlen. In der Landwirtschaft, wo die Nachfrage vor der Saison zu starken Produktionsspitzen f\u00fchrt, kann die mit dem geschliffenen Verfahren verbundene Zykluszeitverk\u00fcrzung wertvoller sein als die Materialkostenersparnis pro St\u00fcck, da dadurch mehr Zylinder innerhalb des verf\u00fcgbaren Produktionsfensters fertiggestellt werden k\u00f6nnen. In den East Midlands ist ein bedeutender Anteil der Zulieferbetriebe f\u00fcr Landmaschinen angesiedelt, und mehrere Unternehmen berichten von einer Senkung der Gesamtzylinderkosten um 81 bis 181 TP4T beim Umstieg auf geschliffene Zylinderbohrungen bei j\u00e4hrlichen Produktionsmengen von \u00fcber 2.000 Zylinderrohren. Diese Werte variieren stark je nach Bohrungsgr\u00f6\u00dfe und Lieferantenbeziehung. F\u00fcr einen konkreten Kostenvergleich, der auf Ihre Anwendung zugeschnitten ist, kontaktieren Sie uns bitte mit Ihren aktuellen Spezifikationen und Ihrer j\u00e4hrlichen Produktionsmenge.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
