Frequently Asked Questions
Q: What is the 1425-3276 bearing cup designed for?
A: The 1425-3276 is a bearing cup component for manual pallet jack wheel assemblies. This cup is used in load wheel and drive wheel applications for standard manual pallet jacks from Crown, Toyota, Raymond, Yale, and equivalent OEM manufacturers.
Q: What dimensions should I measure before ordering the 1425-3276 bearing cup?
A: Verify the outer diameter, inner bore diameter, and mounting depth. Compare these dimensions against your existing bearing cup or your pallet jack manufacturers parts diagram. Dimensional mismatch will prevent proper bearing assembly and wheel rotation.
Q: Can the 1425-3276 cup be used on electric lift trucks or manual equipment only?
A: The 1425-3276 is specified for manual pallet jack parts only. Do not use this cup on electric lift trucks, electric pallet jacks, or power equipment. Load ratings and bearing geometry are specific to manual operation.
Q: What is the expected replacement interval for the 1425-3276 bearing cup?
A: In typical warehouse service, a bearing cup lasts 4 to 6 years with proper maintenance and lubrication. High-volume picking operations may require replacement within 3 years. Replace when the matching cone exhibits pitting, noise, or rough rotation.
Q: Is the 1425-3276 cup compatible with bearing cones from other part numbers?
A: No. The cup and cone must be purchased and installed as a matched tapered bearing set. Mixing the 1425-3276 cup with a different cone will cause binding, noise, and premature bearing failure. Always replace both components together.
Q: What material is the 1425-3276 bearing cup manufactured from?
A: The cup is produced from hardened steel with a precision-ground internal bore. This hardness resists wear from repeated load cycles and maintains dimensional stability in typical warehouse, retail, and distribution center environments.
