Ball Bearing Assembly for Pallet Jacks

Frequently Asked Questions

Q: What are the specifications for the 21035-51H01 bearing assembly?
A: The 21035-51H01 is a ball bearing assembly designed for manual pallet jack load wheel and steer wheel applications. This bearing assembly is compatible with multiple OEM manual pallet jack models from Crown, Toyota, and Raymond. The assembly integrates into the wheel hub for load-bearing or directional control. Verify your equipment model and wheel diameter match this part number before ordering.

Q: Which manual pallet jack models use the 21035-51H01 bearing assembly?
A: The 21035-51H01 fits manual pallet jack models across Crown, Toyota, Raymond, Yale, and Hyster product lines. Compatibility depends on your specific pallet jack model year and wheel hub design. Cross-check your equipment serial number and current bearing assembly part number to confirm fitment. Contact us with your equipment details for exact compatibility verification.

Q: What materials are used in the 21035-51H01 bearing assembly?
A: The 21035-51H01 uses hardened steel ball bearings with sealed or shielded races depending on application. The bearing races are heat-treated steel for durability under continuous load cycling. Seals or shields provide containment for bearing lubricant and protection against contamination in warehouse and loading dock environments.

Q: How long does the 21035-51H01 bearing assembly typically last?
A: Expected lifespan depends on load, frequency of use, and maintenance. Under normal warehouse operation with regular bearing lubrication, this assembly typically functions for 2 to 4 years before replacement. Worn bearings cause wheel drag, noise during operation, or wobbling during load handling. If wheels spin with less resistance than normal or make grinding sounds, bearing replacement is due.

Q: Are there equivalent bearing assemblies to the 21035-51H01?
A: Yes, equivalent bearing assemblies may exist under alternative OEM part numbers from Crown, Toyota, Raymond, and other manufacturers. The 21035-51H01 may cross-reference to different part numbers depending on your equipment brand and model. Confirm internal bearing dimensions, hub bore diameter, and outer race diameter before substituting equivalent parts. Contact us with your current part number for cross-reference options.

Q: How do I know if the 21035-51H01 bearing assembly matches my pallet jack?
A: Measure the wheel hub bore diameter and outer bearing race diameter on your current assembly. Verify your equipment model and serial range against our compatibility chart. Compare the bearing assembly part number visible on your pallet jack wheel hub to the 21035-51H01. Provide these details to our team and we will confirm fitment before you order.
