Wheel cylinder
Frequently Asked Questions
Q: What is a wheel cylinder and what does it do?
A: SKU 446256 is a wheel cylinder that converts hydraulic brake pressure from the master cylinder into mechanical force to apply brake pads or shoes against the wheels. Each wheel has one or more cylinders that receive fluid pressure and push pistons outward to engage the brake.
Q: What forklift brands use this wheel cylinder?
A: This wheel cylinder is compatible with Crown, Toyota, Raymond, Yale, and Hyster forklift models with hydraulic braking systems. Confirm your equipment brake system type (drum or disc), bore diameter, and piston travel distance before ordering to ensure correct fit and function.
Q: What is the construction material of this wheel cylinder?
A: The wheel cylinder body is cast iron or aluminum alloy designed to withstand brake pressure cycles (typically 800 to 1,200 PSI). Internal seals are synthetic rubber (EPDM or NBR) formulated to resist brake fluid degradation and temperature extremes.
Q: How long does a wheel cylinder typically last?
A: Wheel cylinder lifespan depends on brake usage, fluid maintenance, and contamination exposure. In typical forklift service, expect 3,000 to 8,000 operating hours. Moisture in brake fluid, high operating temperatures, and frequent brake applications accelerate seal degradation.
Q: What are the symptoms of a failing wheel cylinder?
A: Signs of wheel cylinder failure include soft or spongy brake pedal, uneven brake application (one wheel drags), visible brake fluid leakage around the wheel, brake fade under load, and brake fluid appearing dark or contaminated.
Q: Are there OEM part numbers equivalent to SKU 446256?
A: SKU 446256 is a direct replacement for original equipment wheel cylinders in Crown, Toyota, Raymond, and other major forklift brands. For specific OEM part number cross-reference, consult your equipment manual or contact our technical support with your equipment serial number.
