Frequently Asked Questions
Q: What are the bearing specifications for the TO 00590-04885-81-A load wheel assembly?
A: This assembly uses 25mm precision bearings made from chrome steel SAE 52100. The bearing material provides durability and corrosion resistance for extended service in warehouse environments. Bearings are pre-installed and ready for equipment mounting.
Q: How does the TO 00590-04885-81-A compare to the standard TO 00590-04885-81?
A: Both wheels share identical dimensions: 4.00 inch diameter, 2.88 inch width, and 25mm bearing bore with 95A Shore durometer polyurethane. The -A suffix indicates Toyota OEM assembly specification. Choose based on your exact equipment model and serial range.
Q: What is the service factor rating for the TO 00590-04885-81-A?
A: The wheel has a nominal service factor of 1.0, indicating standard duty rating for typical warehouse material handling applications. Do not exceed manufacturer load limits to prevent premature bearing wear and wheel degradation.
Q: Is the TO 00590-04885-81-A compatible with non-Toyota electric lift trucks?
A: The 4.00 inch diameter and 25mm bore make this wheel compatible with similar Crown, Raymond, and Yale equipment using identical load wheel socket specifications. Cross-reference your equipment documentation to confirm fitment before ordering.
Q: What core material composition does the TO 00590-04885-81-A use?
A: The wheel features a machined steel core embedded directly in the polyurethane tread for structural integrity and load distribution. This core material provides superior durability compared to cast iron alternatives in high-cycle applications.
