Frequently Asked Questions
Q: What are the wheel dimensions for the CR 83970-50-A?
A: The CR 83970-50-A measures 3.25 inches in outer diameter with a 4.50 inch tread width. The 30mm bore diameter accommodates standard Crown axle fittings on GPW series pallet trucks.
Q: Will this load wheel fit my Crown GPW pallet truck?
A: Yes. The CR 83970-50-A is engineered as a direct replacement for Crown GPW Series equipment. Confirm your pallet truck model designation matches GPW before ordering to ensure proper compatibility.
Q: What are the alternative part numbers for this wheel assembly?
A: Cross-reference numbers include CR83970-50-A, CR8397050A, and 8397050A. These designations identify the same direct replacement part and lead to identical wheel specifications.
Q: What is Durarun polyurethane and why does it matter?
A: Durarun is Crown's proprietary polyurethane formulation rated at 95A durometer. It is engineered for consistent load distribution and tread contact in warehouse and dock environments. Durarun provides extended service life and superior abrasion resistance compared to standard polyurethane compounds.
Q: How long does the CR 83970-50-A typically last?
A: Lifespan depends on load cycles, floor conditions, and maintenance. The sealed bearing system supports extended service cycles in standard indoor material handling operations. When excessive tread wear or bearing failure occurs, the entire wheel assembly is replaced as a unit.
Q: What surfaces are suitable for this load wheel?
A: The CR 83970-50-A is rated for standard indoor material handling including warehouse distribution and dock operations. Polyurethane tread provides adequate grip on concrete, sealed concrete, and similar hard-surface floors. For specialized environments like cold storage, verify material compatibility with Crown specifications before use.
Q: Are sealed bearings factory-sealed?
A: Yes. The sealed bearing system is integrated into the wheel assembly at the factory and requires no maintenance. This design minimizes downtime and extends service intervals in material handling operations.
