PM20023

Frequently Asked Questions

Q: What equipment does the PM20023 bearing assembly fit?
A: The PM20023 is a replacement bearing assembly for manual pallet jacks, designed for load wheel and steer wheel applications. It is compatible with Crown, Toyota, Raymond, Yale, Hyster, and equivalent manual pallet jack models that use OEM part number PM20023.

Q: What type of bearing construction is used in the PM20023?
A: The PM20023 is a sealed deep groove ball bearing manufactured from high-carbon chromium bearing steel. The sealed design prevents contamination and moisture ingress, which extends service life in warehouse and dock environments.

Q: Is the PM20023 bearing pre-lubricated, and how long does it last?
A: Yes, the PM20023 comes factory pre-lubricated and sealed. Under normal manual pallet jack duty cycles, sealed bearings typically last 3 to 5 years before showing wear symptoms. Bearing life depends on load cycles, floor conditions, and maintenance practices. Replace when you notice wheel resistance or noise.

Q: Can the PM20023 be used in both load wheel and steer wheel positions?
A: Yes, the PM20023 bearing assembly is designed for use in both load wheel and steer wheel assemblies. Verify that your jack model uses the same bearing size and bore diameter for both wheel positions before ordering multiple units.

Q: What maintenance does the PM20023 bearing require after installation?
A: The PM20023 is sealed and factory lubricated, so no additional lubrication is required after installation. Periodic inspection for noise or resistance during normal jack operation is recommended. Do not attempt to open or re-lubricate the sealed bearing.
