Frequently Asked Questions

Q: What equipment does precision bearing assembly SKU 18643 fit?
A: SKU 18643 is a precision bearing assembly designed for manual pallet jack load wheels and steering wheel support. It is compatible with standard manual pallet jacks from Crown, Toyota, Raymond, Yale, and similar manufacturers. Verify the bearing bore and mounting dimensions match your specific equipment model.

Q: What are the material specifications for SKU 18643?
A: SKU 18643 features precision-machined alloy steel races and bearing surfaces. The bearing is oil-lubricated with sealed contact for debris resistance. Machined races provide tighter tolerances and smoother operation compared to standard bearings, extending service life in typical warehouse pallet jack duty.

Q: How does SKU 18643 precision bearing differ from standard bearings?
A: Precision bearings like SKU 18643 have tighter manufacturing tolerances, better surface finish, and superior sealing compared to basic bearings. This results in smoother wheel rotation, lower noise, reduced vibration, and longer service life. Precision bearings handle moderate to heavy-duty warehouse cycles more reliably.

Q: What is the load capacity and service life of SKU 18643?
A: SKU 18643 is rated for dynamic and static loads typical to manual pallet jack wheel assemblies, generally 4000 to 5500 pounds per wheel set in standard warehouse use. Actual service life depends on load cycles, maintenance, and operating environment. Properly lubricated precision bearings typically deliver 3 to 5 years of service.

Q: How often should SKU 18643 be inspected or re-lubricated?
A: Inspect SKU 18643 bearing assembly every 500 operating hours or quarterly. Check for wheel play, noise, or grinding. Re-lubricate or top off oil levels at the same interval if your equipment design allows field lubrication. Sealed precision bearings may be sealed-for-life and not require maintenance during normal warehouse use.

Q: Is there a cross-reference part number for SKU 18643?
A: SKU 18643 is the primary reference for this precision bearing assembly. Contact our parts team with your equipment model and serial number if you need to confirm compatibility or identify equivalent OEM part numbers from your specific pallet jack manufacturer.
