Frequently Asked Questions
Q: What does Shore 95A rating mean for the CR 312021-A?
A: Shore 95A indicates a moderately firm polyurethane compound that balances durability and floor protection. This rating suits heavy-load and long-run applications where wheels must resist cutting while minimizing surface damage. Shore 95A is slightly softer than 97A, providing slightly better grip on smoother floors.
Q: What are the dimensions of the CR 312021-A load wheel assembly?
A: The CR 312021-A has a 5-inch outside diameter, 2.44-inch inside diameter, and 4.12-inch tread width. It features shoulder bearing construction and polyurethane tread bonded to a steel hub. These dimensions are specific to Crown 300 Series lift trucks; verify compatibility with your equipment model.
Q: What is the load capacity of the CR 312021-A?
A: The CR 312021-A is rated for heavy-load applications in Crown 300 Series lift trucks. Exact load capacity depends on the truck model, number of wheels, and load configuration. Consult your Crown equipment documentation for maximum load specifications to ensure safe operation and proper wheel selection.
Q: What bearing configuration does this wheel use?
A: The CR 312021-A uses shoulder bearing construction, which provides radial support and is common in electric lift truck load wheel assemblies. Shoulder bearings center the wheel on the axle and distribute loads across the bearing surface, enabling smooth rotation under heavy loads during long runs.
