Bearing Assembly

Frequently Asked Questions

Q: What is the difference between single shield and double shield bearing assemblies?
A: Single shield bearing assemblies have one removable or fixed protective cover on one side of the bearing. Double shield assemblies have covers on both sides, providing greater contamination resistance. The CK654301 single shield design is suitable for cleaner warehouse environments where some protection from debris is needed but full sealing is not required.

Q: Which pallet jack applications are best suited for the CK654301 single shield bearing?
A: The CK654301 single shield bearing is designed for manual pallet jacks, hand trucks, and load wheels used in standard indoor warehouse and distribution environments. It provides cost-effective contamination protection without the extra expense of fully sealed bearings, making it ideal for non-washdown applications.

Q: Does the CK654301 require lubrication or maintenance?
A: The single shield design allows for periodic lubrication if required by your equipment manufacturer. Check your pallet jack documentation to determine if open or shielded bearings should be greased. Many warehouse bearing assemblies are pre-lubricated and require no field maintenance during normal use.

Q: When should I upgrade from the CK654301 to a sealed bearing assembly?
A: Consider switching to sealed bearings if your operation includes washdown cleaning, wet floors, cold storage, or outdoor equipment use. The single shield CK654301 is not rated for high-moisture or contamination-heavy environments where sealed or double shield designs perform better and maintain lifespan.
