Frequently Asked Questions
Q: What is a bearing cup and how does it differ from a bearing cone?
A: A bearing cup is the outer tapered race of a tapered roller bearing assembly. Unlike the cone, the cup is stationary and mounts inside the wheel hub bore. The cup provides the fixed raceway surface while the cone rotates on the axle, and together they support the rolling elements.
Q: What pallet jack models and brands is SKU 671-023-06 bearing cup compatible with?
A: This bearing cup (671-023-06) fits manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, Clark, Mitsubishi, Jungheinrich, Linde, CAT, and BT. Confirm the cup outer diameter and bore width match your wheel hub specifications to ensure proper seating and bearing preload.
Q: What material composition does this bearing cup have?
A: The bearing cup is manufactured from case-hardened steel with a hardened and ground tapered raceway surface. This material is selected to resist the concentrated loads from the rolling elements and provide durability across thousands of operational hours in warehouse and material handling environments.
Q: How can I tell if a bearing cup is failing and needs replacement?
A: Signs of bearing cup wear include grinding or squealing noises from the wheel assembly, visible spalling or pitting on the raceway surface, lateral movement of the wheel on the axle, and resistance to smooth rolling. Any of these symptoms indicates the cup should be inspected and replaced to prevent further bearing damage.
Q: What is the expected service life of SKU 671-023-06?
A: Under normal warehouse conditions with regular maintenance, a bearing cup typically lasts 2-5 years before degradation requires replacement. Lifespan varies based on load weight, surface conditions, storage environment, and maintenance practices such as lubrication and cleaning.
Q: Should I replace the bearing cone and cup together or separately?
A: Bearing cone and cup should be replaced as a matched pair for optimal performance and to maintain proper bearing preload. If only the cup shows wear, inspect the cone carefully. Installing a new cup with a worn cone will cause rapid wear and potential bearing failure due to misalignment and uneven load distribution.
