Bearing Assembly

Frequently Asked Questions

Q: What equipment does bearing assembly 29021-31K20 fit?
A: This bearing assembly is compatible with manual pallet jack wheel and steering assemblies from Crown, Toyota, Raymond, and Yale. Verify your equipment model and serial range before ordering to confirm fitment with your specific unit.

Q: What is the construction and material of 29021-31K20?
A: This is a precision-machined bearing assembly with hardened steel races and steel ball or roller elements. Internal components are factory-packed with grease for rotational support. The steel is treated with corrosion-inhibiting lubricant to resist wear in typical warehouse environments.

Q: How long does a bearing assembly typically last in manual pallet jack service?
A: Under normal load handling conditions, a properly maintained bearing assembly will provide 3 to 5 years of service. Lifespan depends on load frequency, floor conditions, and whether the bearing receives regular lubrication. Wet or salt environments reduce service life.

Q: What are the failure symptoms of a worn bearing assembly?
A: Worn bearings produce grinding or squeaking noise during wheel rotation, increased rolling resistance requiring more operator effort, and lateral wheel play or wobble. If wheels do not spin freely or emit grinding sounds, the bearing assembly likely needs replacement.

Q: Does 29021-31K20 require special maintenance?
A: The bearing assembly comes factory-packed with grease. Periodic inspection is recommended every 6 to 12 months, depending on usage intensity. If the bearing is not sealed, occasional re-greasing may extend lifespan. Do not over-grease, as excess lubricant can attract dirt.

Q: Are there cross-reference part numbers for 29021-31K20?
A: No established cross-reference or superseded part numbers are currently available for this assembly. Always reference your equipment documentation and confirm the exact SKU 29021-31K20 matches your wheel or steering assembly to ensure proper fit.
