Frequently Asked Questions

Q: What equipment does AP SC-4088 bearing assembly fit?
A: AP SC-4088 is a bearing assembly for manual pallet jacks compatible with Crown, Toyota, Raymond, Yale, and other major OEM pallet jack manufacturers. Verify your specific pallet jack model number before ordering to ensure correct fit.

Q: What material is AP SC-4088 made from?
A: AP SC-4088 is manufactured from hardened steel components designed to withstand repeated load cycles and impact. The bearing cup and cone are precision-manufactured to tight tolerances for reliable performance in warehouse operations.

Q: How does AP SC-4088 differ from AP SC-4080?
A: Both AP SC-4088 and AP SC-4080 are bearing assemblies for manual pallet jacks, but they may have different bore sizes, outer dimensions, or design specifications. They are not interchangeable. Confirm which assembly is correct for your equipment model.

Q: What is the expected service life of AP SC-4088?
A: Service life depends on load conditions, floor surfaces, and operating environment. Under typical warehouse use with proper equipment maintenance, bearing assemblies last several years. Replace when grinding noise, wheel play, or resistance develops.

Q: Can AP SC-4088 be used in cold storage or wet environments?
A: AP SC-4088 can be used in cold storage and wet environments, but bearing life will be reduced due to corrosion and condensation exposure. Inspect bearings more frequently in these applications and plan for earlier replacement.

Q: What symptoms indicate AP SC-4088 needs replacement?
A: Replace the bearing assembly when you hear grinding or squealing from the wheel area, feel excessive play when rotating the wheel by hand, experience increased rolling resistance, or observe rust on the bearing cup or cone surface.
