Bearing Assembly

Frequently Asked Questions

Q: What pallet jack models use the APSC-4112 bearing assembly?
A: The APSC-4112 bearing assembly is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, and Hyster. Fitment depends on load wheel diameter, axle diameter, and your specific model year. Verify your pallet jack model and serial range before ordering.

Q: What is the load rating for the APSC-4112 bearing assembly?
A: Load rating for the APSC-4112 varies by configuration. Typical manual pallet jack bearing assemblies support between 3000 and 6000 pounds per wheel depending on bearing size and material. Contact us with your pallet jack model to confirm the exact load rating for your application.

Q: How often should the APSC-4112 bearing assembly be greased?
A: Bearing assemblies typically require greasing every 250-500 operating hours or every 6 months in normal conditions. In wet environments or cold storage, increase greasing to monthly intervals. Use a general-purpose lithium-based grease compatible with material handling equipment unless your manufacturer specifies otherwise.

Q: What failure symptoms indicate the APSC-4112 needs replacement?
A: Replace the APSC-4112 if you observe grinding noises from the wheel, visible wobble or play, resistance to rotation, or rust on bearing surfaces. These symptoms indicate internal damage or corrosion that cannot be corrected by greasing alone. Delayed replacement may damage the axle and wheel.

Q: How long does the APSC-4112 bearing assembly typically last?
A: Under normal warehouse use with regular greasing, the APSC-4112 typically lasts 2-4 years. In high-cycle or outdoor environments, expect 12-24 months. Cold storage and wet conditions reduce lifespan to 12-18 months due to accelerated corrosion and seal degradation.

Q: Are there equivalent cross-reference part numbers for the APSC-4112?
A: Cross-reference compatibility depends on your pallet jack OEM and model. Contact us directly with your equipment model and serial number, and we will verify if the APSC-4112 is the correct replacement and identify any equivalent OEM part numbers.
