40562058

Frequently Asked Questions

Q: What material is the bearing assembly 40562058 constructed from?
A: The 40562058 is a sealed ball bearing assembly manufactured from SAE 52100 high-carbon chromium steel with a stamped steel cage. The raceway and ball components meet a minimum Rockwell C58 hardness specification. Dual rubber seals protect against contamination in warehouse environments. This material composition provides extended durability in high-load manual pallet jack applications.

Q: Which manual pallet jack models does bearing 40562058 fit?
A: The 40562058 is compatible with Uline Standard manual pallet jacks, Lift Rite L50 models, Crown PTH50 units, and comparable manual pallet jack models from other major manufacturers. This bearing functions as a load wheel or steer wheel assembly component. Verify your equipment model and bearing cavity dimensions match specification before ordering.

Q: What is the tolerance class and ISO rating for bearing 40562058?
A: The 40562058 is manufactured to ISO tolerance class P0, which is the standard tolerance grade for general-purpose bearing applications. This tolerance class ensures consistent fit and performance across replacement cycles while maintaining acceptable clearance in typical manual pallet jack wheel hubs.

Q: How do the dual rubber seals on bearing 40562058 benefit warehouse operations?
A: The dual rubber seals on the 40562058 provide protection against moisture, dust, and debris ingress common in high-load warehouse environments. Sealed construction reduces bearing wear from environmental contamination and extends service life compared to unsealed bearings. The seals also reduce maintenance requirements in damp or outdoor storage conditions.

Q: Are there cross-reference part numbers for bearing assembly 40562058?
A: No OEM cross-reference part numbers have been confirmed for the 40562058. Contact our parts team with your equipment make, model, and bearing cavity dimensions if you need compatibility verification or alternative part options.
