Frequently Asked Questions
Q: What is part number 935?

Q: Which lift truck models use this mast bearing?
A: This mast bearing is used in electric lift trucks from major OEM manufacturers including Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, and Clark. Confirm your specific equipment model and mast configuration before ordering.
Q: What function does a mast bearing perform?
A: Mast bearings enable smooth vertical travel of mast sections during lift and lower cycles, reduce friction against mast guides, and distribute load across the mast assembly. Proper bearing function is critical for safe and efficient lift truck operation.
Q: What are failure symptoms of a worn mast bearing?
A: Signs of mast bearing wear include rough or jerky mast movement, binding during collapse, lateral mast play or wobble, visible scoring on mast poles, and increased hydraulic load during lift and lower operations. These symptoms indicate bearing replacement is needed.
