3131965

Frequently Asked Questions

Q: What are the dimensions of the 3131965 bearing assembly?
A: The 3131965 is a double-sealed, single-row radial ball bearing with a 20 mm bore, 47 mm outside diameter, and 14 mm width. These dimensions make it compatible with standard load wheel hubs on manual pallet jacks from major manufacturers.

Q: What material is the 3131965 bearing constructed from?
A: The 3131965 is manufactured from SAE 52100 high carbon chrome steel. This material provides hardness and wear resistance required for manual pallet truck load wheel applications. The double-sealed design prevents contamination and extends bearing life in material handling environments.

Q: Which pallet jack brands use the 3131965 bearing assembly?
A: The 3131965 bearing is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other manufacturers using standard 20 mm bore load wheel assemblies. Verify that your equipment uses a 47 mm outside diameter, 14 mm width bearing before ordering.

Q: Why are sealed bearings used on manual pallet truck load wheels?
A: Sealed bearings prevent dust, moisture, and debris from entering the bearing cavity, which reduces friction, minimizes wear, and extends service life. The double-seal design on the 3131965 is especially important in warehouses and outdoor environments where contamination is common.

Q: How long does a 3131965 bearing typically last in service?
A: Bearing lifespan depends on load, frequency of use, and maintenance. SAE 52100 sealed bearings like the 3131965 typically provide 2 to 5 years of service on manual pallet jacks in normal warehouse conditions. Regular inspection for noise or resistance indicates when replacement is needed.
