Frequently Asked Questions
Q: What is AP SC-4074 and what does it do?
A: AP SC-4074 is a bearing cup component used in manual pallet jack wheel assemblies. It provides the raceway surface that supports the rolling bearing elements and transfers the load to the wheel structure.
Q: Which manual pallet jack brands use AP SC-4074?
A: AP SC-4074 is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, and other major OEM manufacturers. Check your equipment documentation or bearing assembly for the exact model designation to confirm fitment.
Q: What dimensions should I verify before ordering AP SC-4074?
A: Confirm the bore diameter, outer diameter, and thickness of the bearing cup match your wheel assembly. Mismatched dimensions will result in improper load distribution and premature failure. Measure or reference your current part before ordering.
Q: How does AP SC-4074 compare to similar bearing cups like AP SC-4049?
A: Both AP SC-4074 and AP SC-4049 are bearing cups, but they may differ in bore size, outer dimensions, or design profile. They are not interchangeable without verification. Confirm the exact fit for your equipment model.
Q: When should AP SC-4074 be replaced?
A: Replace the bearing cup when you notice visible spalling or pitting on the inner raceway surface, grinding noise during equipment operation, or excessive play in the wheel assembly. These symptoms indicate the cup raceway is degraded.
