Frequently Asked Questions
Q: What is the CK731292 bearing cup and what does it replace?
A: The CK731292 is a bearing cup component, which is the stationary outer race in a tapered roller bearing assembly. This cup sits in the wheel hub bore and provides the raceway surface for the rolling elements. It is commonly replaced as part of preventive maintenance or when bearing assemblies are rebuilt.
Q: What manual pallet jack models use the CK731292 bearing cup?
A: The CK731292 bearing cup is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and Jungheinrich load wheel assemblies. Verify the cup bore size and depth dimensions match your equipment hub bore before ordering to ensure proper fit.
Q: What material is the CK731292 bearing cup manufactured from?
A: The CK731292 bearing cup is manufactured from hardened alloy steel with a precision-ground raceway surface. The hardened construction resists deformation under heavy radial and axial loads typical of pallet jack wheel assemblies under full capacity.
Q: How do I know if my bearing cup needs replacement?
A: Disassemble the bearing assembly and inspect the inner raceway surface. Signs of replacement include visible spalling, pitting, or scoring on the raceway, loss of raceway surface finish, or corrosion. If the cone (inner race) shows wear, the cup is often replaced as a matched set for optimal bearing performance.
