Description
Forklift Attachment Cylinder — Φ90mm, 265mm Stroke
Model HCYY11112029 | Φ90×Φ45×265 | 18 MPa Working Pressure | 26 kg

When a forklift attachment demands consistent, repeatable force under continuous shift conditions, the hydraulic cylinder at its heart cannot be an afterthought. The Forklift Attachment Cylinder HCYY11112029 — bore diameter 90 mm, rod diameter 45 mm, and stroke 265 mm — is engineered for precisely those demands. Rated at a working pressure of 18 MPa and tested to a maximum withstand pressure of 24 MPa, this cylinder delivers the kind of controlled linear actuation that keeps warehouse logistics, port handling, and industrial material-transfer operations running without interruption. Across busy distribution centres in England, Scotland, and Wales, where forklifts run double shifts and attachment cycles run into the thousands per week, performance margins matter enormously. This cylinder has been designed from the rod seal inward to meet those margins reliably.
Technical Specifications

How This Cylinder Works — Principle, Material & Application
Operating Principle
Pressurised hydraulic oil enters the cylinder barrel through the port on the cap end, driving the piston — and the attached rod — outward through the stroke of 265 mm. When oil is directed to the rod-end port, the piston retracts. A differential area between cap-end and rod-end surfaces gives the extend stroke greater force, which is precisely what forklift attachment tilting and clamping mechanisms require. The tight 18 MPa working envelope ensures the cylinder remains within a safe fatigue range across thousands of daily actuation cycles typical in UK logistics operations.
Material & Construction
The barrel is honed from seamless cold-drawn steel tube, delivering a surface finish that extends seal life by eliminating micro-scoring. The piston rod — 45 mm diameter — is precision-ground and hard chrome-plated to a depth that resists corrosion from condensation common in cold-store environments across British warehousing. Internal seals combine polyurethane and NBR compounds selected for compatibility with standard ISO VG 46 hydraulic oil. End caps are machined from ductile iron, and all external threads are protected with anti-corrosion coatings suited to the UK’s moisture-heavy climate.
Typical Applications (UK Sectors)
This forklift attachment cylinder is well-suited to side-shifters, rotators, push-pull attachments, and carton clamps used across UK distribution hubs, food and beverage production facilities, and NHS supply-chain logistics centres. Its compact 500 mm installation distance keeps it practical on attachments with limited mounting space. Forklift operators throughout the East Midlands logistics corridor and Scottish central belt distribution parks have found the stroke-to-installation ratio particularly useful when retrofitting ageing attachment frames without modifying pin centres.

Customer Success Story
Reducing Forklift Downtime by 40% at a Major UK 3PL Operator
A third-party logistics (3PL) provider operating a 200,000 sq ft distribution facility in Nottingham was experiencing frequent unplanned downtime on their fleet of 18 counterbalance forklifts, each fitted with paper-roll clamp attachments. The existing attachment cylinders — sourced from a different supplier — were showing premature seal failure after roughly 8 months of service, causing unscheduled halts during peak e-commerce fulfilment windows. The maintenance team contacted our UK sales desk for an alternative. After reviewing their hydraulic circuit data and attachment load cycles, we recommended the HCYY11112029 for its tighter bore tolerance and upgraded multi-lip seal pack.
We supplied a first batch of 36 cylinders with custom port orientations to suit the existing attachment frames, eliminating any hose re-routing cost. Installation was completed over a single weekend by the client’s in-house engineering team using our dimensional drawings. Over the following 14 months, the facility recorded zero cylinder-related downtime events and reported a 40% overall reduction in planned hydraulic maintenance hours. The client subsequently placed a standing order covering their Birmingham and Sheffield sites.
What UK Customers Say
“We’ve been running these cylinders on our Cascade rotators for over a year. Zero leaks, smooth stroke every time. The hard chrome rod holds up well in our cold store — nothing like the pitting we had with our old supplier’s parts.”
“Ordered the 90mm units for eight of our push-pull attachments. Dimensions were spot on — fitted without any modification to our existing mounting pins. The quote turnaround was fast and shipping arrived within the agreed lead time.”
“We manage a fleet of 40 forklifts across three Scottish sites. Sourcing reliable attachment cylinders at a fair price has always been a headache. Boom Cylinders made the process simple — clear specs, honest pricing, and the cylinders perform as described. Highly recommended.”
Manufacturing Capability & Custom Orders
Our manufacturing facility operates a full production line for hydraulic cylinders — from raw steel tube honing through to final pressure testing. We hold ISO-certified quality management processes and run dedicated inspection stations for dimensional verification, leak testing at 1.5x working pressure, and surface finish measurement before any cylinder leaves the line.
