Frequently Asked Questions

Q: What is the purpose of a bearing cup in a pallet jack wheel assembly?
A: A bearing cup is the outer raceway component of a tapered roller bearing that supports the wheel hub and load wheel assembly on manual pallet jacks. The cup works with a bearing cone to provide smooth, low-friction rotation under load.

Q: What are the specifications for SKU 0062-7809?
A: This bearing cup has an inside diameter of 20 mm, outside diameter of 47 mm, and width of 14 mm. It features a double sealed design with Rockwell C58 hardened raceways for extended wear resistance.

Q: What material is the 0062-7809 bearing cup made from?
A: This bearing cup is constructed from precision-engineered carbon steel with hardened raceways minimized to Rockwell C58. The hardened raceway surface provides superior wear resistance and smooth rolling surfaces.

Q: What is the benefit of pre-lubrication on this bearing cup?
A: Pre-lubrication extends maintenance intervals by delivering factory-applied lubricant to bearing contact surfaces. This reduces the frequency of manual re-greasing and maintains bearing performance during initial operation.

Q: How long does a bearing cup typically last before replacement?
A: A properly maintained bearing cup typically lasts 3 to 5 years depending on load cycles, operating hours, and maintenance. Bearing cups used in heavy-duty or outdoor applications may require earlier replacement.

Q: How do you know if the 0062-7809 bearing cup needs replacement?
A: Replace the bearing cup if you observe grinding noise from the wheel assembly, excessive wheel play, visible pitting or scoring on the raceway surface, or rough rotation. Worn cups should be replaced as a paired set with the bearing cone.
