Replacement Bearing Assembly for Manual Pallet Jacks

Frequently Asked Questions

Q: What is the MH040005 bearing assembly and what equipment does it fit?
A: The MH040005 is a replacement bearing assembly for manual pallet jack load and steering wheels. Designed for standard manual pallet jacks, it is compatible with equipment from major OEM manufacturers such as Crown, Toyota, Raymond, Yale, Hyster, and similar brands that use standard bearing interfaces. Verify your equipment specifications match before ordering.

Q: What material is the MH040005 constructed from?
A: The MH040005 is constructed from case-hardened bearing steel with an oil-impregnated, non-plated finish. Case hardening provides a tough outer surface while maintaining ductility in the core, delivering both load capacity and impact resistance needed in manual pallet jack applications. The oil impregnation aids in corrosion resistance and reduces friction during operation.

Q: What are the key dimensions and bore specifications of the MH040005?
A: The MH040005 bearing assembly is designed with a 20 mm bore, 47 mm outer diameter, and 14 mm width, matching standard manual pallet jack wheel mounting interfaces. These dimensions provide direct interchange compatibility with most generic manual pallet jack bearing requirements.

Q: How does the oil-impregnated finish affect durability and maintenance?
A: The oil-impregnated, non-plated finish provides inherent lubrication and corrosion protection without requiring external coating or frequent relubrication. This design minimizes maintenance needs and extends bearing life, particularly in moisture-prone environments. The finish protects the bearing races from oxidation while reducing friction during wheel rotation.

Q: What is the expected service life of the MH040005 bearing assembly?
A: Under typical warehouse conditions with standard load cycles, expect 20 to 40 months of service life. The case-hardened steel construction and oil-impregnated finish support extended durability. Heavy-load applications, high-frequency use, or contaminated floor conditions may reduce service life. Replace when bearing rotation becomes rough or noisy.
