Frequently Asked Questions

Q: What are the specifications and dimensions for the LFM50400004 bearing assembly?
A: The LFM50400004 is a sealed ball bearing assembly with precision dimensions of 20 mm bore diameter, 47 mm outer diameter, and 14 mm width. It features heat-treated chrome steel construction with double-lip rubber seals designed for reliable warehouse operation in manual pallet jack load and steer wheel applications.

Q: Which pallet jack models does the LFM50400004 bearing fit?
A: The LFM50400004 is compatible with Lift-Rite manual pallet jacks. It fits standard pallet jack wheel hubs across load and steer wheel applications. Verify your equipment model and wheel hub dimensions match the 20x47x14 mm specifications before ordering.

Q: What materials are used in the LFM50400004 bearing assembly?
A: The LFM50400004 uses heat-treated chrome steel for the bearing races and balls, providing durability and wear resistance in warehouse environments. Double-lip rubber seals protect against debris, moisture, and contaminants during normal pallet jack operation.

Q: How long does the LFM50400004 bearing last in normal warehouse use?
A: Bearing lifespan depends on load, frequency of use, and maintenance. The sealed design with double-lip seals minimizes debris entry and extends service life. Regular inspection for noise, grinding, or lateral play indicates when replacement is needed. Sealed bearings cannot be relubricated and must be replaced as complete assemblies.

Q: Will the LFM50400004 fit pallet jacks from brands other than Lift-Rite?
A: The LFM50400004 is designed for Lift-Rite equipment. However, it may fit other manual pallet jacks with identical wheel hub dimensions (20x47x14 mm), such as certain models from Vestil, Roughneck, or generic warehouse equipment. Always verify wheel hub bore diameter, outer diameter, and width match exactly before purchase.
