Frequently Asked Questions
Q: What equipment is the SU S9135-XL wheel compatible with?
A: The SU S9135-XL is designed for Crown electric pallet jacks and similar electric lift trucks that accept a 3.25 inch diameter load wheel with a 1.938 inch bore. This wheel fits mid-range electric pallet jack models from Crown and compatible third-party equipment using standard load wheel mounts. Verify your equipment documentation lists a 3.25 x 5 wheel specification before ordering.
Q: What is the difference between the SU S9135-XL wheel and the SU S9135-XL-A assembly?
A: The SU S9135-XL is a wheel only with a steel core surface finished for bonding. The SU S9135-XL-A is a complete assembly that includes the same polyurethane wheel plus pre-installed precision bearings ready to mount. If your jack needs only the wheel element, choose the S9135-XL. If you need a plug-and-play ready assembly, the S9135-XL-A saves assembly labor.
Q: What does 97A durometer Cushothane XL compound mean for performance?
A: The 97A Shore durometer rating indicates a hard, load-bearing polyurethane that resists compression and wear under heavy continuous duty. Cushothane XL is Superior Industries proprietary formulation that delivers enhanced grip, longer service life in indoor/outdoor environments, and reduced noise compared to standard polyurethane. XL3 bonding technology ensures the poly compound stays bonded to the steel core even under shock loads.
Q: How long does the SU S9135-XL wheel typically last before replacement?
A: Lifespan depends on duty cycle and surface conditions. In moderate indoor warehouse use, expect 18-24 months. In heavy continuous use or rough outdoor surfaces, life may drop to 12-18 months. Monitor the wheel for flat spots, cracking, or loss of grip. If the wheel surface becomes visibly worn or the jack pulls to one side, replacement is needed regardless of calendar time.
Q: What maintenance does the SU S9135-XL wheel require?
A: Weekly: inspect the wheel for debris, cracks, or flat spots and clean with a damp cloth. Monthly: check that the wheel spins freely and does not wobble when the jack is idle. Do not use solvents or pressure washers that can degrade the polyurethane bond. If the wheel develops a flat spot or loses roundness, do not attempt to repair it; replacement is the only safe option.
Q: Is the SU S9135-XL equivalent to any other brand load wheels?
A: The SU S9135-XL shares the same 3.25 x 5 inch dimensions and 1.938 inch bore with many competitor load wheels from manufacturers like Hyster, Yale, and Toyota. However, the Cushothane XL 97A compound and XL3 bonding are Superior-specific. If your equipment was originally fitted with a competitor wheel, verify that the bore and core material match before substituting the SU S9135-XL.
