POLY LOAD WHEEL (95A)
Frequently Asked Questions
Q: What is the load rating and hardness rating for the SU S523 poly load wheel?
A: The SU S523 is a polyurethane load wheel rated at 95A shore hardness. This medium-hardness formulation balances load capacity with floor traction for general-purpose electric lift truck applications. Verify your truck model specification sheet to confirm 95A is correct for your equipment.
Q: Is the SU S523 wheel compatible with my electric lift truck, and are there equivalent part numbers I should know about?
A: The SU S523 fits most standard lift truck wheel hubs with a 20 mm bore. Always verify your current wheel diameter and width against the SU S523 spec sheet before ordering. Cross-check your truck manufacturer part number (Yale, Toyota, Crown, Hyster, etc.) to confirm compatibility. If your truck requires assembly labor or hub replacement, contact your dealer.
Q: How do I diagnose if my SU S523 wheels need replacement?
A: Replace wheels if you observe flat spots, chunking, visible wear down to the hub, reduced traction on smooth floors, or vibration during operation. Inspect wheels every 500 operating hours. If the tread is worn below 1/8 inch thickness or the wheel is cracked, it must be replaced.
