Q: What is the tread material durometer on the CR 83179-050-XL?
A: The CR 83179-050-XL features premium 97A Shore A polyurethane. This compound is harder than standard 95A, providing extended wear life and lower floor noise on smooth warehouse floors.
Q: What cross-reference part numbers apply to the CR 83179-050-XL?
A: The CR 83179-050-XL supersedes the earlier CR 83179-050, is equivalent to CR 083179, and cross-references to house brand GW 9143-A. Related OEM assemblies include CR 115374-001 and CR 115374-002.
Q: What bearing specification is used in the CR 83179-050-XL?
A: The wheel is equipped with a precision 6205 2RS sealed deep groove ball bearing. The 2RS designation indicates sealed contact on both sides, protecting internal races from moisture and dust ingress.
Q: How long does a CR 83179-050-XL wheel typically last in normal warehouse operations?
A: Expected service life is 18 to 30 months under normal warehouse conditions. The 97A compound extends wear compared to standard 95A wheels. Accelerated wear occurs on rough concrete, outdoor environments, or with excessive dock leveler impacts.
