Frequently Asked Questions
Q: What equipment does the 640068 bearing assembly fit?
A: The 640068 is a sealed bearing assembly for manual pallet jack wheel applications. It is compatible with standard pallet jacks from manufacturers such as Crown, Toyota, Raymond, Yale, and Hyster. Verify your bearing bore dimensions before ordering.
Q: What is the expected lifespan of the 640068 bearing?
A: In typical manual pallet jack service with normal load and operation, the 640068 bearing generally performs for 2 to 4 years before replacement. High-volume or rough facility conditions may reduce this service life.
Q: Why does the 640068 bearing have seals?
A: The seals on the 640068 bearing serve two functions: they retain bearing grease inside the bearing races, and they prevent dirt, dust, and moisture from entering. This extends bearing life and reduces maintenance requirements in warehouse environments.
Q: Can I re-grease the 640068 bearing assembly?
A: The 640068 is a sealed bearing with factory-packed grease. Sealed bearings are not designed for re-greasing; attempting to open the seals to add grease will damage the bearing. Replace the bearing when grease leakage or increased drag occurs.
