Frequently Asked Questions
Q: What are the specifications for the CR 82021-25 load wheel assembly?
A: The CR 82021-25 features a 6 inch outside diameter, 2.75 inch tread width, 3.14 inch bearing bore, and Shore A 95A polyurethane tread. This larger wheel is designed for Crown electric lift trucks requiring extended load capacity and reach.
Q: What is the CR 82021-25 wheel designed for in terms of load and use?
A: The CR 82021-25 is engineered for long runs, heavy load handling, and challenging floor conditions. The 6 inch diameter and soft 95A polyurethane tread provide better shock absorption and stability under sustained heavy-load operation compared to smaller wheel assemblies.
Q: How does the CR 82021-25 differ from the CR 82021-040 wheel?
A: The CR 82021-25 is a larger wheel with 6 inch diameter versus 5 inch on the CR 82021-040. The bearing bore is 3.14 inch compared to 2.44 inch, and tread width is 2.75 inch versus 4.12 inch. The CR 82021-25 is rated for heavier sustained loads and longer operational cycles.
Q: Which Crown electric trucks are compatible with the CR 82021-25?
A: The CR 82021-25 is a premium assembly for Crown electric lift trucks designed for heavy-duty applications. Verify your truck model and serial range support the 6 inch wheel diameter and 3.14 inch bearing bore before ordering. Do not interchange with 5 inch wheel assemblies.
Q: Why choose soft 95A polyurethane for this wheel assembly?
A: Shore A 95 polyurethane on the CR 82021-25 balances tread life with floor grip and shock absorption. This compound is ideal for long runs and heavy loads because it reduces vibration on uneven floors and extends tire life under continuous high-load operation compared to harder compounds.
Q: What maintenance is required for the CR 82021-25 bearing bore?
A: The 3.14 inch bearing bore includes precision bearings engineered for heavy-load service. Monitor for noise or resistance during operation. The bearing assembly is sealed, so avoid submersion in water or cleaning with high-pressure water spray. Replace the entire wheel assembly if bearing damage occurs.
