Description
HCYY11112002 Forklift Steering Cylinder — Rear-Axle Hydraulic Steering
The HCYY11112002 is the steering cylinder in the HCYY11112000 forklift cylinder series, controlling the lateral movement of the rear steering wheels. As a double-acting hydraulic cylinder, it provides powered steering in both left and right directions — essential on a counterbalance forklift where the rear-steer geometry and relatively small rear wheels require hydraulic assist to achieve the tight turning radius that indoor material handling demands. The cylinder’s low-friction seal package is specifically selected to maintain consistent, light steering effort across the full range of rear axle loads, from unladen to maximum rated capacity.

Rear-Steer Forklift Steering System
How the Steering Cylinder Connects to the Orbitrol
The hydraulic steering circuit on a counterbalance forklift uses an orbitrol (steering control unit) — a hydrostatic metering unit that proportions hydraulic flow to the steering cylinder in direct proportion to handwheel rotation. Turning the handwheel pumps hydraulic oil to the cylinder’s extend or retract port; releasing the handwheel closes the orbitrol spool and holds the cylinder — and therefore the wheels — in the set position. The HCYY11112002 is designed to interface with standard orbitrol output pressures and flows used in counterbalance forklift hydraulic systems.
Why Low Steering Effort Matters
In high-intensity picking operations where a forklift operator steers continuously for 6–8 hours, steering cylinder seal friction directly affects operator fatigue. Each additional 0.5 Nm of handwheel effort from cylinder friction accumulates to thousands of extra Newton-meters of steering work across a shift. The HCYY11112002’s low-friction seal compound maintains the designed steering effort throughout its service life, not just at initial installation.
