Dual-Action Aerial Vehicle Steering Cylinder (100×2 Stroke)

Dual-Action Precision

Bi-directional hydraulic force gives operators accurate left–right steering authority without mechanical play, critical on uneven ground or sloped construction sites.

High-Pressure Tolerance

Maximum withstand pressure of 15 MPa — 50% above working pressure — provides a substantial safety margin for shock loads and pressure spikes encountered on rough terrain platforms.

Compact & Lightweight

At just 7 kg with a 645 mm installation distance, the unit integrates into confined chassis spaces without adding unnecessary mass that would affect platform load ratings.

Seal System Engineered for UK Climate

Polyurethane wiper seals and NBR inner seals cope reliably with the UK’s temperature swings from near-freezing winters to warm summers, preventing ingress of water and debris common on British outdoor worksites.

Hard-Chrome Rod Surface

The Φ25 mm piston rod undergoes hard-chrome plating to HRC 58–62, delivering corrosion resistance and surface hardness that extend seal life and maintain dimensional accuracy through repeated cycles.

Drop-In OEM Replacement

Mounting interfaces match common aerial platform OEM specifications, meaning UK maintenance teams can install a replacement cylinder in the field without custom machining or adapter brackets.

Operating Principle

Pressurised hydraulic oil enters either the cap-end or rod-end port, pushing the piston along the bore in the desired direction. Because the cylinder is double-acting, both extension and retraction are powered — eliminating the reliance on spring return or gravity that limits single-acting designs. The dual-stroke architecture (100 mm + 100 mm) allows the geometry to handle the full left-lock to right-lock arc of a typical articulated aerial platform in a single compact package, keeping the turning radius tight and the steering response linear across the full travel range. Internal cushioning at both end positions softens the piston’s arrival, reducing mechanical shock that would otherwise shorten the service life of the mount pins and vehicle chassis brackets.

Material Composition

The cylinder barrel is drawn from 45# seamless steel tube, cold-drawn and precision-honed to a bore finish of Ra 0.4 µm. The piston rod is produced from 40Cr alloy steel, turned to h8 tolerance, hard-chrome plated to a minimum 25 µm depth, and then polished to Ra 0.2 µm to minimise seal friction. End caps are machined from forged steel and threaded directly to the barrel body, avoiding welded joints that might introduce residual stress. The piston seal package combines a PTFE-backed guide ring with a Hallite-type U-cup that maintains zero-leak performance from -20°C to +80°C — a range comfortably encompassing all conditions encountered on outdoor UK construction and maintenance projects.

Result

Unscheduled hydraulic maintenance incidents reduced by approximately 70% across the trial fleet. The contractor has since placed an annual standing order covering full fleet cylinder replacement cycles.

We fitted these steering cylinders to our entire scissor platform fleet operating on construction sites around Birmingham. Eighteen months later, not a single leak. The build quality is noticeably better than what we were sourcing from the previous supplier at a higher price point.

We were sceptical about switching suppliers mid-contract, but the technical data sheets and pressure test certificates gave us the confidence to proceed. The cylinder dimensions were spot-on for our Genie units and the installation took less than an hour per machine.

Ordered 20 units for a bridge inspection project in Scotland. Delivery was within the quoted lead time, packaging was solid, and each cylinder came with its own test documentation. Our engineers were impressed with the consistency across the batch — every unit measured within tolerance.
