SU S9820

Frequently Asked Questions

Q: What material is the SU S9820 poly load wheel made from?
A: The SU S9820 features a molded polyurethane tread bonded to a high-tensile steel core, machined for dimensional accuracy. The polyurethane compound provides floor protection, resists oils and chemicals, and delivers low rolling resistance. The steel core ensures structural integrity under heavy loads and continuous industrial operation.

Q: Which electric lift truck models use the SU S9820 wheel?
A: The SU S9820 is intended for electric lift trucks and powered pallet jacks that require this specific wheel size and bore diameter. No cross-reference part numbers have been published for this SKU. Contact us with your lift truck model, serial number, and current wheel specifications to confirm exact fitment and availability of equivalent wheels from other manufacturers if needed.

Q: Can I replace the SU S9820 wheel with a different brand wheel?
A: Yes, if the replacement wheel has the same bore diameter, hub bore tolerances, and wheel width. Mismatched bore sizes will cause wobbling or excessive play on the axle. Wheels that are too wide may rub the frame or fenders. We recommend matching original wheel specifications exactly. Contact us to verify equivalent wheels that fit your specific lift truck model.

Q: What is the load capacity of the SU S9820 wheel?
A: Load capacity is not determined by the wheel alone but by your lift trucks axle and frame rating. Refer to your trucks nameplate for maximum rated load. The SU S9820 is engineered for continuous industrial duty on electric lift trucks; it will not fail under normal load conditions if the truck is rated for that load. Exceeding your trucks rated capacity will damage bearings, axles, and wheels.

Q: How do I know when the SU S9820 wheel needs replacement?
A: Replace the SU S9820 when you observe flat spots, visible flat wear areas, tread thickness reduced to less than 3mm, chunks or tears in the polyurethane, or resistance and grinding noise during operation. If the wheel has yellowed or hardened from age and heat exposure, traction and flexibility are compromised and replacement is recommended. Inspect quarterly during routine maintenance.

Q: What is the expected lifespan of the SU S9820 wheel in normal operation?
A: Expected lifespan is 12-24 months under typical 8-hour daily operation on standard indoor concrete floors. Harsh conditions including rough or dirty concrete, outdoor use, wet floors, cold storage, or continuous heavy loading reduce lifespan to 6-12 months. Wheels operated in extreme temperature environments (below 32 degrees Fahrenheit or above 120 degrees Fahrenheit) may harden faster and require earlier replacement.
