Frequently Asked Questions
Q: What is the 56378259 bearing cup used for?
A: The 56378259 bearing cup is an outer raceway component for manual pallet jack load wheel assemblies. It works in tandem with a bearing cone to support rotating wheel axles and distribute load under continuous use.
Q: What equipment models is the 56378259 compatible with?
A: This bearing cup is engineered for manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, and other major OEM manufacturers. Confirm your equipment model and axle assembly before ordering to ensure correct fitment.
Q: What materials and specifications define this bearing cup?
A: The 56378259 is constructed from hardened alloy steel with precision machining to tolerance specifications required for ball or roller bearing compatibility. The hardened surface provides extended durability under warehouse load cycling.
Q: How does bearing cup wear affect pallet jack performance?
A: Worn bearing cups create internal play, leading to noise, vibration, wheel resistance, and uneven load distribution across the load wheel assembly. This increases wear on the matching cone and can compromise safety and control during operation.
Q: Do I need to order the bearing cone separately with this cup?
A: Yes, bearing cups and cones are sold separately and must be matched as a pair for your specific equipment. Contact us with your pallet jack model details and we will provide the correct cone part number to pair with the 56378259 cup.
