Frequently Asked Questions
Q: What equipment is the CR 77084-XL-A load wheel assembly compatible with?
A: The CR 77084-XL-A is designed for Crown PW Series electric pallet trucks. It is interchangeable with Crown OEM part numbers 77084-A and CR77084-A. The shoulder bearing assembly and bore tolerances are engineered for PW Series mounting interfaces. Verify your specific equipment model before ordering.
Q: What are the dimensions of the CR 77084-XL-A assembly?
A: The CR 77084-XL-A features a 5 inch outside diameter, 2.88 inch tread width, and 2.44 inch bore diameter. The shoulder bearing assembly adds structural support for the axle interface. These dimensions are specific to Crown PW Series equipment and are not compatible with other manufacturers without verification.
Q: What polyurethane compound and hardness does the CR 77084-XL-A use?
A: The CR 77084-XL-A uses a polyurethane compound with Durarun 95A Shore A hardness rating. The machined polyurethane tread is engineered for enhanced longevity in demanding material handling environments. The 95A durometer provides balanced wear resistance and load support across varied floor conditions.
Q: What cross-reference part numbers match the CR 77084-XL-A?
A: The CR 77084-XL-A replaces and is equivalent to 77084-A and CR77084-A. It also supersedes earlier part number 77084. When ordering, use the exact part number CR 77084-XL-A or the manufacturer format CR77084-XL-A to ensure receipt of the correct shoulder bearing assembly configuration and bore specifications.
Q: How does the shoulder bearing assembly affect wheel performance?
A: The shoulder bearing assembly reduces radial and axial movement, preventing binding and wear on the mounting axle. This design extends bearing life and provides more consistent wheel tracking. Inspect the shoulder bearing for side-to-side play or noise, which indicates wear. Replace the assembly when bearing movement is detected or polyurethane tread shows uneven wear patterns.
