Frequently Asked Questions

Q: What are the specifications of the C666178 deep groove ball bearing?
A: The C666178 bearing has a 20 mm bore diameter, 47 mm outer diameter, and 14 mm width. It features a double shielded construction which protects the bearing races and rolling elements from contamination and moisture in material handling environments.

Q: What manual pallet jack brands use the C666178 bearing assembly?
A: The C666178 is compatible with manual pallet jack models from Crown, Toyota, Raymond, Yale, Hyster, and similar industrial material handling equipment manufacturers. Use this bearing in load wheel and pivot point assemblies across these brands.

Q: What material is the C666178 bearing made from and how durable is it?

Q: How long does the C666178 bearing typically last before replacement is needed?
A: Bearing lifespan depends on load capacity usage, operating environment, and maintenance practices. Under normal warehouse conditions, the C666178 typically lasts 3 to 5 years. Excessive noise, grinding, or resistance when spinning the wheel indicates replacement is needed.

Q: Can the C666178 bearing be used in both load wheel and pivot assemblies?
A: Yes. The C666178 deep groove ball bearing is designed for use in both load-carrying wheel assemblies and steering pivot point assemblies on manual pallet jacks. Verify mounting dimensions and bore fit before installation.
