Frequently Asked Questions
Q: What are the exact dimensions of the CR 312021-003-A load wheel?
A: The CR 312021-003-A features a 6-inch tread diameter, 2.88-inch width, and 3.149-inch inside diameter. The hub is machined steel with polyurethane bonded tread and shoulder bearing construction. Verify these dimensions match your Crown 300 Series equipment before ordering.
Q: What does Shore 97A hardness mean for this load wheel?
A: Shore 97A indicates a firm polyurethane compound that resists cutting and abrasion in heavy-duty environments. This hardness rating suits long runs, heavy loads, dock boards, and floors with debris. Harder compounds (higher Shore rating) provide better wear resistance on rough surfaces.
Q: Which Crown lift truck models use the CR 312021-003-A?
A: The CR 312021-003-A is engineered for Crown 300 Series electric lift trucks. It is rated for long-run and heavy-load applications. No cross-reference part numbers exist for this SKU, so confirm your equipment model and serial range match Crown 300 Series specifications before installation.
Q: How long does this load wheel typically last?
A: Load wheel lifespan depends on floor conditions, load weight, and usage frequency. Polyurethane wheels like the CR 312021-003-A generally last 12 to 36 months in moderate to heavy-use environments. Rough floors with debris accelerate wear. Monitor for uneven tread wear, flat spots, or reduced traction as replacement indicators.
