MAST BEARING
Frequently Asked Questions
Q: What is SKU 710048 mast bearing used for?
A: The 710048 mast bearing supports the vertical load cell and mast assembly in manual pallet jacks. It reduces friction between the mast and chassis, allowing smooth vertical movement when the handle is operated.
Q: Which pallet jack brands use the 710048 bearing?
A: This bearing is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, and Hyster. Verify your equipment model and serial range match before ordering, as bearing fitment varies by mast height and chassis design.
Q: How long does the 710048 bearing last under normal operation?
A: Expected service life is 3 to 5 years with standard warehouse use (8 to 12 hours daily). High-frequency operation in dense materials or outdoor environments may reduce lifespan. Lack of maintenance or exposure to moisture accelerates wear.
Q: What are the failure symptoms of a worn mast bearing?
A: Symptoms include grinding or squeaking noise during mast operation, rough or jerky vertical movement, increased effort required to lift the handle, and lateral play or wobbling of the mast assembly.
Q: Does the 710048 need maintenance or lubrication?
A: This bearing is factory-lubricated and sealed. Periodic inspection for contamination or damage is recommended. Do not disassemble or relubricate; replace as a complete unit when wear symptoms appear.
