Frequently Asked Questions
Q: What are the specifications of the SU S9141-XL load wheel?
A: The SU S9141-XL measures 3.250 inches outer diameter by 6.500 inches tread width with a 1.938-inch inner bore diameter. Durometer hardness is 97A Shore A, providing superior wear resistance. The wheel uses Cushothane XL polyurethane compound formulated for extended-life, heavy-duty warehouse cycles.
Q: Which pallet jack models are compatible with the SU S9141-XL?
A: The SU S9141-XL fits electric and manual pallet jacks from Crown, Toyota, Raymond, Yale, and Hyster that use 3.25-inch diameter wheels with 6.5-inch width load-bearing assemblies. Related variants include SU S9141-XL-A (assembly version) and SU S9141-XL-C3 (alternate configuration). Verify hub width and bearing ID against your truck documentation.
Q: Why does the SU S9141-XL have a 97A Shore hardness rating?
A: The 97A Shore A hardness provides a balance between load-carrying capacity and floor grip. This mid-range hardness resists abrasion and cuts on rough concrete, reduces noise during acceleration and braking, and maintains traction on smooth warehouse floors. Softer compounds (90A) offer more grip but wear faster; harder compounds (100A+) last longer but reduce traction.
Q: How do I install the SU S9141-XL on my pallet jack?
A: Position the jack on a level surface and remove the load. Unbolt the axle assembly holding the worn wheel. Slide the SU S9141-XL onto the axle shaft, ensuring the hub bore seats fully onto the bearing. Verify free rotation without binding. Reinstall and torque the axle fasteners per manufacturer specifications. Do not operate if rotation feels rough or binding.
Q: What is the service life of the SU S9141-XL in heavy-duty applications?
A: In continuous heavy-duty warehouse service, the SU S9141-XL typically lasts 24 to 36 months. XL formulation and 97A hardness extend life versus standard wheels. Replace wheels when tread wear reaches 50 percent depth, cracks appear, or the hub begins to separate from the polyurethane layer. Regular inspection every quarter prevents sudden failures.
