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. The shoulder bearing assembly and bore tolerances are engineered specifically for PW Series mounting interfaces. It is a direct replacement for part numbers 77084-A and CR77084-A. Verify your specific equipment model before ordering.
Q: What are the key dimensions of the CR 77084-XL-A assembly?
A: These dimensions are specific to Crown PW Series equipment. The shoulder bearing assembly adds structural support for the axle interface.
Q: What material and hardness rating does the CR 77084-XL-A use?
A: The CR 77084-XL-A uses a polyurethane compound with Durarun 95A Shore A hardness. The machined tread is engineered for enhanced longevity in demanding material handling environments, providing balanced wear resistance and load support across varied floor conditions.
Q: What part numbers are equivalent to the CR 77084-XL-A?
A: The CR 77084-XL-A is a direct replacement for 77084-A and CR77084-A, and 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 performance and maintenance?
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 consistent wheel tracking. Inspect the shoulder bearing periodically for side-to-side play or noise, which may indicate wear. Replace the assembly when bearing movement is detected or when polyurethane tread shows uneven wear patterns.
