Frequently Asked Questions

Q: What components are included in the 28700-370 bearing assembly?
A: The 28700-370 is a complete bearing assembly that typically includes the outer race (cup), inner race (cone), rolling elements (balls or rollers), and retainer. This is a ready-to-use unit for replacement in manual pallet jack wheel and load systems.

Q: What manual pallet jack models is the 28700-370 bearing assembly compatible with?
A: The 28700-370 bearing assembly fits multiple manual pallet jack models from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Confirm bearing dimensions and bore size match your equipment specifications before ordering.

Q: What is the expected lifespan of the 28700-370 bearing assembly?
A: Under normal warehouse duty with regular maintenance and proper storage, the 28700-370 bearing assembly typically lasts 3 to 5 years or 2000 to 4000 operating hours. Harsh conditions such as wet floors, extreme temperatures, or continuous heavy loading will reduce this lifespan significantly.

Q: What causes premature failure of bearing assemblies like the 28700-370?
A: Common causes of premature bearing failure include water or moisture contamination, inadequate lubrication, misalignment during fitment, operating beyond rated load capacity, and lack of periodic inspection. Cold storage and wet-floor environments accelerate bearing deterioration.
