Frequently Asked Questions
Q: What is the CR 83179-050-XLL wheel assembly made from?
A: The assembly features a cast iron hub core with polyurethane tread bonded to the casting. Cast iron provides superior load distribution and dimensional stability for long-cycle material handling applications.
Q: What bearing is used in the CR 83179-050-XLL and what size is the bore?
A: This assembly uses a sealed deep groove ball bearing (6205-2RS) with a 25 millimeter bore. The sealed design prevents contaminant entry in high-volume warehouse and dock environments.
Q: Is the CR 83179-050-XLL a direct replacement for Crown PE 4000 Series equipment?
A: Yes, the CR 83179-050-XLL is a direct replacement for Crown PE 4000 Series electric pallet jacks. It matches factory-spec dimensions and performance standards for this equipment line.
Q: What is the tread hardness of the CR 83179-050-XLL?
A: The tread features 98A Shore A polyurethane compound, a premium heavy-load-capacity formulation designed for sustained high-capacity operations where standard 95A or 97A compounds would experience accelerated wear.
Q: What other part numbers cross-reference to the CR 83179-050-XLL?
A: Cross-reference numbers include 083179-050, 83179-201-A, and CR 083179-050-XL. Verify your equipment documentation to confirm compatibility before ordering.
Q: What environments are suitable for the CR 83179-050-XLL?
A: This wheel assembly performs reliably on dock boards, expansion joints, in wet conditions, across metal chips, and on debris-laden floors typical of active material handling operations.
Q: How should the CR 83179-050-XLL be stored when not in use?
A: Store in a cool, dry location away from direct sunlight and extreme temperatures. Keep the bearing sealed to prevent moisture and contamination accumulation during extended storage periods.
Q: What is the diameter of the CR 83179-050-XLL load wheel?
A: The wheel diameter is 4.00 inches, sized for standard Crown PE 4000 Series electric pallet jack specifications.
