OEM Bearing Assembly for Pallet Jack Wheels

Frequently Asked Questions

Q: What is the 305S bearing assembly used for?
A: The 305S is an OEM bearing assembly with a single shield designed for manual pallet jack load wheel and caster applications. It is supplied as a single assembly per sleeve and functions as a direct replacement component for worn or damaged bearings in standard pallet jack wheel assemblies.

Q: What is the difference between a single shield and double shield bearing?
A: Single shield bearings like the 305S have protection on one side only, allowing for slightly lower operating temperatures and reduced friction. Double shield bearings like the 305DD provide sealing on both sides for maximum contamination protection. Single shield designs work well in relatively clean environments, while double shield is preferred in wet or dirty conditions.

Q: What pallet jack equipment types is the 305S compatible with?
A: The 305S bearing is compatible with manual pallet jacks from major manufacturers including Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Confirm that your equipment specifies the OEM 305S number before ordering.

Q: How many bearings are needed per wheel assembly?
A: Most pallet jack wheel assemblies require one bearing per side of the wheel. The 305S is supplied as a single assembly, so order the quantity based on how many wheel positions require replacement on your equipment.

Q: When should the 305S bearing be replaced?
A: Replace the 305S bearing when you hear grinding or squealing sounds from the wheel, feel rough resistance during wheel rotation, or notice excessive play or wobbling in the wheel. Continuing to operate with damaged bearings will cause accelerated wear to wheels and equipment frames.
