Wheel cylinder
Frequently Asked Questions
Q: What function does wheel cylinder SKU 220012668 perform on a forklift?
A: Wheel cylinder 220012668 is a hydraulic brake component that converts hydraulic pressure into mechanical force to actuate the brake pads or shoes against the wheel. This cylinder is essential for safe braking operation in industrial lift truck applications.
Q: Which forklift brands and models use wheel cylinder 220012668?
A: SKU 220012668 is designed for forklifts manufactured by Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, and Mitsubishi. Confirm compatibility by verifying the bore diameter, mounting bolt pattern, and hydraulic port configuration match your equipment.
Q: What are the critical specifications of this wheel cylinder?
A: Key specifications include internal bore diameter (which determines output force), port thread size, overall length, and mounting configuration. These dimensions are matched to the vehicle hydraulic system pressure rating and brake shoe/pad force requirements.
Q: How long does a wheel cylinder last before replacement is needed?
A: Under normal forklift duty, a wheel cylinder typically lasts 3-5 years. Lifespan depends on brake usage frequency, hydraulic fluid condition, and maintenance. Longer service life occurs with lighter braking patterns and well-maintained hydraulic systems.
Q: What symptoms indicate wheel cylinder 220012668 has failed?
A: Failure symptoms include soft or spongy brake pedal, brake drag on one wheel, brake fluid leaks near the wheel, or loss of braking force. Any loss of braking function requires immediate cylinder replacement for safe operation.
Q: What is the internal construction of wheel cylinder 220012668?
A: The wheel cylinder contains precision-manufactured pistons, seals, and springs. The bore surface must be smooth and straight for proper seal function. Internal corrosion or pitting from contaminated hydraulic fluid causes seal failure and external leakage.
