Frequently Asked Questions
Q: What is the difference between SU 487-XL and other 8 x 2.5 wheels?
A: The SU 487-XL features a cast iron core with polyurethane tread bonded using the XL3 chemical bond system. This construction provides a no-bond separation guarantee, meaning the tread remains permanently adhered to the core even under heavy shock loads. Other wheels may use mechanical bonding methods that risk separation during impact, making the SU 487-XL superior for high-vibration or rough-surface environments.
Q: Can the SU 487-XL be used as a direct replacement for my trucks current load wheels?
A: Yes, the SU 487-XL is engineered as a direct replacement for standard 8 x 2.5 electric lift truck wheel assemblies. Verify that your truck currently uses 8 x 2.5 wheels by measuring diameter and width, and confirm that the 1.938 inch inside diameter and 0.785 inch bore depth match your existing axle setup. If your truck uses different dimensions or a special hub configuration, the SU 487-XL may not be compatible.
Q: What load capacity does the SU 487-XL wheel support?
A: The SU 487-XL 8 x 2.5 wheel is typically rated for 4000 to 5500 lbs per wheel depending on bearing configuration, hub width, and truck design. The cast iron core provides superior load distribution compared to aluminum hubs. For exact load specifications, consult your lift truck manual or contact the manufacturer with your truck model and serial number.
Q: What floor surfaces are safe for the SU 487-XL?
A: The SU 487-XL with polyurethane tread operates safely on concrete, tile, vinyl, and sealed wood floors. Do not use on unsealed wood, wet clay, or outdoor unpaved surfaces, as the polyurethane compound can degrade under UV exposure and the wheel may stick or skip on uneven terrain. For outdoor applications, consider pneumatic or solid urethane alternatives.
Q: How often should I replace the SU 487-XL wheel?
A: Replace the SU 487-XL when tread is worn to less than 0.1875 inches or when cracks appear in the polyurethane outer layer. Typical service life is 1500 to 3000 operating hours depending on load duty and floor conditions. Inspect quarterly for tread wear and bond separation by attempting to peel the polyurethane from the cast iron core with moderate hand pressure. If separation occurs, retire the wheel immediately.
