Frequently Asked Questions
Q: What is a bearing cup and what does it do in a manual pallet jack?
A: A bearing cup is a precision raceway component that houses ball or roller bearings in the load wheel assembly of a manual pallet jack. It supports the wheel on the axle and distributes load evenly. The cup works with a matching cone to create a tapered roller bearing assembly that allows smooth wheel rotation under load.
Q: Which manual pallet jack models use K8000-02775?
A: K8000-02775 is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, and Hyster equipment that use standard tapered roller bearing assemblies in their load wheel carriages. Verify your equipment model and serial number range before ordering to confirm fitment.
Q: What material is this bearing cup made from?
A: This bearing cup is manufactured from alloy steel and is precision-machined to exacting tolerances. The hardened raceway surface resists wear and corrosion, providing long service life in standard warehouse and indoor material handling environments.
Q: When should I replace a worn bearing cup?
A: Replace the bearing cup when you observe excessive wheel play, grinding noise during operation, flat spots or spalling on the raceway surface, or uneven wheel wear. Worn bearing cups must be replaced as a matched set with their corresponding cone component to maintain proper alignment and load distribution.
Q: Are there equivalent part numbers for K8000-02775?
A: Cross-reference your equipment documentation for OEM bearing cup part numbers. Different manufacturers use different numbering systems. K8000-02775 is the standard identifier for this specific bearing cup; always verify dimensions and bore diameter match your load wheel axle before substituting alternate parts.
