Frequently Asked Questions
Q: What does Shore 95A rating mean for this load wheel?
A: Shore 95A indicates a moderately firm polyurethane compound that balances durability and floor protection. This rating is ideal for heavy-load and long-run applications where wheels must resist cutting while minimizing surface damage to warehouse floors. Shore 95A is softer than 97A, providing enhanced grip and floor compatibility.
Q: What are the dimensions of the 312021-A load wheel assembly?
A: It uses shoulder bearing construction with polyurethane tread bonded to a steel hub.
Q: What bearing configuration does this wheel use?
A: The 312021-A uses shoulder bearing construction, which provides radial support and is standard in electric lift truck load wheel assemblies. Shoulder bearings center the wheel on the axle and distribute loads evenly across the bearing surface, enabling smooth rotation under heavy loads during extended run times.
Q: What is the intended application for the 312021-A?
A: This wheel assembly is designed for heavy-load and long-run applications in Crown 300 Series electric lift trucks. The Shore 95A polyurethane compound and shoulder bearing design deliver the durability and performance needed in demanding warehouse and material handling environments with frequent use cycles.
Q: How do I verify this wheel is compatible with my Crown equipment?
A: Cross-reference the 312021-A part number with your Crown equipment's parts documentation or service manual. The '300 Series' designation indicates the intended Crown truck line. Contact Crown Equipment or your authorized parts distributor if you need confirmation that this wheel fits your specific truck model.
Q: Is this a direct replacement for Crown wheels?
A: Yes, the 312021-A is a direct replacement load wheel assembly for compatible Crown 300 Series lift trucks. It is manufactured to factory-spec standards and maintains original equipment performance and durability. Always verify your truck model compatibility before ordering.
