Frequently Asked Questions
Q: What is a bearing cup and where does it fit?
A: A bearing cup (SKU 7003903) is the stationary outer race of a tapered roller bearing assembly. It sits in the housing bore of manual pallet jack wheel hubs, pump assemblies, or mast components. Verify the bore diameter and cup bore size match your pallet jack model.
Q: Which manual pallet jack brands use this bearing cup?
A: SKU 7003903 is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Jungheinrich, Linde, and Clark. Bearing cups are often interchangeable across models from the same manufacturer. Always verify the cup bore ID and OD dimensions before ordering.
Q: What material is this bearing cup made from?
A: This bearing cup (SKU 7003903) is typically made from hardened alloy steel with a precision-ground raceway surface. The hardened steel provides durability under the cyclic loading common in pallet jack wheel assemblies.
Q: What are the signs of a worn bearing cup?
A: Symptoms of bearing cup wear include wheel wobble, noise or grinding sounds during operation, rough wheel rotation, and premature bearing cone wear. If the cup raceway is pitted or spalled, replace both the cup and matching cone to restore proper load distribution.
