Frequently Asked Questions
Q: What are the key specifications for the CR 83587 load wheel?
A: The CR 83587 is a 5 inch diameter polyurethane load wheel designed for Crown RS Reach Trucks. It features a 4.125 inch tread width, 35 mm bore ID, and 6307-ZZ ball bearings. The polyurethane compound has a hardness rating of 90 Shore A durometer, providing durability in standard material handling applications.
Q: Which equipment types is the CR 83587 compatible with?
A: The CR 83587 is specifically designed for Crown RS Reach Trucks and other electric lift trucks in the material handling equipment category. Verify that the 5 inch diameter and 35 mm bore ID match your equipment before ordering, as fitment requirements vary by model and year.
Q: What does the 90 Shore A durometer rating mean for this wheel?
A: The 90 Shore A durometer indicates medium-to-hard polyurethane hardness. This provides good resistance to wear and cuts while maintaining adequate grip on standard indoor and outdoor flooring. Harder durometers generally have longer service life but may reduce traction in wet conditions.
Q: What bearing type does this load wheel use and why does it matter?
A: The CR 83587 uses 6307-ZZ ball bearings. The ZZ designation means the bearings have metal shields on both sides for protection against dust and moisture. This bearing type is standard for material handling equipment and provides reliable rotation under load conditions.
Q: How long do I expect this load wheel to last in typical use?
A: Load wheel lifespan depends on usage intensity, floor conditions, and maintenance. The polyurethane compound and 6307-ZZ bearings are designed for extended service life in warehouse and distribution center environments. Monitor for uneven wear, flat spots, or grinding noises as indicators that replacement is needed.
