Bearing Assembly

Frequently Asked Questions

Q: What manual pallet jack models use the 504-K-37 bearing assembly?
A: The 504-K-37 bearing assembly is designed for manual pallet jacks from Crown, Toyota, Raymond, Yale, Clark, Mitsubishi, and other OEM manufacturers. Confirm your pallet jack model, year, and serial range match before ordering.

Q: What are the physical dimensions of the 504-K-37?
A: The 504-K-37 is a sealed bearing assembly with specific bore diameter and width dimensions. Measure the existing bearing on your pallet jack and cross-reference the specification sheet to verify the 504-K-37 is the correct replacement.

Q: How does the 504-K-37 perform in cold storage or wet environments?
A: The 504-K-37 uses industrial-grade seals and grease designed for standard warehouse conditions. For extended cold storage or high-moisture applications, verify grease type compatibility with your storage temperature. High-performance bearing assemblies with specialized lubricants may be required for extreme conditions.

Q: What load capacity does the 504-K-37 bearing assembly support?
A: The 504-K-37 is rated for standard manual pallet jack loading, typically 3000 to 5500 pounds depending on mounting location and fork configuration. Overloading or side-loading beyond rated capacity causes premature bearing failure.

Q: Can the 504-K-37 be disassembled and cleaned if it gets contaminated?
A: The 504-K-37 is a sealed assembly and not designed for disassembly or field cleaning. If bearings become contaminated with dirt, water, or debris, the seals have already failed and the entire assembly must be replaced to prevent damage to pallet jack components.

Q: What cross-reference part numbers exist for the 504-K-37?
A: The 504-K-37 serves as a direct replacement for OEM bearing assemblies across multiple pallet jack brands. Related assemblies include 504-K-32, 504-K-33, and 504-K-353, but each is designed for specific equipment types or mounting locations. Verify the correct SKU using your pallet jack service documentation.
