SU S9160-XL-A

Frequently Asked Questions

Q: What electric lift truck models are compatible with the SU S9160-XL-A 6 inch load wheel?
A: The SU S9160-XL-A is a 6 inch diameter by 2.88 inch width polyurethane load wheel designed for electric pallet jacks, stackers, and platform trucks. A 6 inch wheel is commonly found on larger capacity electric jacks and warehouse stackers. Verify compatibility by measuring your existing wheel or consulting your equipment specification tag. The bore diameter is 2.947 inches and the bore depth is 1.43 inches. If your truck currently uses a different size wheel (such as 4 inch or 3.25 inch), do not attempt to fit the SU S9160-XL-A without confirming your hub design can accommodate the larger diameter.

Q: Is SU S9160-XL-A equivalent to any cross-brand wheel part numbers?
A: The SU S9160-XL-A is a 6 x 2.88 load wheel assembly. Many material handling equipment manufacturers use the same standard wheel size. If you have documentation from your equipment showing cross-reference part numbers from Crown, Toyota, Raymond, Yale, Hyster, or other brands, a 6 x 2.88 wheel from those OEMs may be equivalent if the bore and hub configuration match. However, core material and tread durometer may differ between suppliers. Verify bore diameter (2.947 inches), bore depth (1.43 inches), and hub width (2.88 inches) against your existing wheel before substituting brands.

Q: What materials and durometer rating does the SU S9160-XL-A use?
A: The SU S9160-XL-A uses Cushothane XL polyurethane tread material. The core is steel or composite depending on OEM specification and vehicle design. Cushothane XL provides non-marking tread that does not leave black rubber residue on floors, and it offers firm grip in standard warehouse conditions. The tread profile is 3/8 inch radius, which provides good contact and durability for high-cycle material handling duty. Cushothane XL is designed for general warehouse use and is not suitable for outdoor, wet, or extreme temperature environments. If your facility uses wet floors or cold storage, contact our technical team to discuss High Traction polyurethane alternatives.

Q: What is the load capacity rating for the SU S9160-XL-A and how many wheels does a truck need?
A: The SU S9160-XL-A is engineered for electric lift truck continuous duty cycles per OEM specification. Actual load capacity depends on your specific truck model and the total number of load wheels installed (typically 4 wheels per truck). The truck OEM documentation will specify the maximum load per wheel. Do not estimate capacity based on wheel size alone. Consult your truck specification plate or OEM manual for total truck load rating and any wheel-specific pressure or load limits.

Q: How do I diagnose whether the SU S9160-XL-A wheel needs replacement?
A: Inspect for flat spots, tread separation, chunks missing from the tread, or cracks radiating from the bore. Listen for grinding or squealing during operation, which indicates bearing damage. Visually check for severe glazing (shiny, slippery surface) that reduces grip. Roll the equipment on a clean, dry floor. If it slides easily or pulls consistently to one side, one or more wheels are failing. If the wheel is 5 or more years old and used daily, it may lose grip due to material aging even if tread appears acceptable. Test grip by pushing the truck forward slowly and observing if it responds evenly to steering input.

Q: What is the replacement procedure and lifespan for the SU S9160-XL-A?
A: Expected lifespan is 3-5 years under normal duty (8 hours per day in a warehouse). Under heavy-duty continuous operation (16+ hours daily), lifespan may be 2-3 years. To replace, lift the truck safely on jack stands, unbolt or press the old wheel off the axle, and install the new SU S9160-XL-A. Ensure the bearing spins freely before lowering the truck. If the wheel is press-fit and you lack a hydraulic press, contact our technical team for guidance. Replace all four load wheels within 6 months of replacing the first wheel to maintain even handling and load distribution.
