Frequently Asked Questions
Q: Is SU S880-XL the same as SUS880-XL-A?
A: Yes. SU S880-XL and the alternate designation SUS880-XL-A are the same poly load wheel assembly. Both refer to the 97A durometer Cushothane XL wheel, 3.25 inch diameter by 6.5 inch width. Use the SKU your system recognizes; no functional difference exists between the two part number formats.
Q: Can I replace a worn S880-XL wheel on a running electric lift truck?
A: No. Always de-energize and fully lower the truck bed before wheel replacement. Block the truck on a level surface and remove all load. Loosen the bearing bolts or retaining clips (depending on your lift model), slide the wheel off the axle stub, inspect the stub and bearing race for wear or damage, and slide the new wheel on. Retorque fasteners to OEM spec and test under no-load first.
Q: What causes premature wear on S880-XL poly wheels?
A: Excessive side-loading (turning at speed with heavy loads), rough concrete, moisture on floors (reduces grip and increases slip), and overloads beyond truck capacity are common causes. 97A durometer polyurethane is rated for smooth to moderate flooring. If wheels wear flat or develop flat spots within 6-12 months of normal use, check for bent axles, misalignment, or load rating violations.
Q: What are the bearing specifications for the S880-XL?
A: The S880-XL has a bore depth of 1.807 inch and bore outside diameter of 2.0467 inch. Inside diameter is 1.938 inch. Standard tapered roller bearings or deep-groove ball bearings fit this size range. If your truck uses sealed cartridge bearings, confirm the bearing type and seal configuration before ordering a replacement wheel to ensure compatibility.
Q: Can S880-XL wheels be used on a different lift truck model?
A: Only if the replacement truck has the same axle shaft diameter (bore specifications) and the same load rating. The S880-XL is 97A polyurethane and designed for electric lift trucks. Verify your truck manual for approved wheel sizes and load limits. Do not force fit a wheel if the bore does not match your axle shaft diameter.
Q: How long does an S880-XL wheel last in typical warehouse use?
A: Under normal operating conditions (8-hour shifts, smooth concrete, loads within truck capacity), expect 18-30 months of service. High-use environments or rough flooring may reduce life to 12-18 months. Inspect wheels monthly for flat spots, cracking, or uneven wear. Replace immediately if you observe chunks missing from the tread or if the wheel does not roll freely.
