Frequently Asked Questions
Q: What is XL3 bonding technology and how does it improve the wheel?
A: XL3 is Superiors proprietary polyurethane bonding technology that creates a stronger molecular bond between the steel core and the polyurethane tread. This prevents delamination and edge cracking that occurs on conventional wheels under heavy stress. XL3 bonded wheels maintain their round shape longer and resist splitting, especially in high-load applications or rough surface environments.
Q: Is the SU S530-XL-A compatible with all electric pallet jacks?
A: The SU S530-XL-A fits any pallet jack or reach truck requiring a 3.25 inch diameter by 1.875 inch width load wheel with a 1.938 inch bore diameter. Before ordering, verify your trucks bore size, axle pin configuration, and the number of wheels you need to replace. Mixing wheel types on the same truck can cause steering instability, so replace all four wheels at the same time when possible.
Q: Can I mix the SU S530-XL-A with other wheel types on the same truck?
A: No. Mixing different wheel types, materials, or wear levels on the same truck creates uneven rolling characteristics and steering problems. If one wheel fails, replace the entire set of four wheels with the same part number. This ensures consistent handling, even braking, and maximum safety during operation. Do not compromise on this safety practice to save cost.
Q: What symptoms indicate the SU S530-XL-A needs replacement?
A: Replace the wheel immediately if you observe flat spots on the tread surface, chunks or tears missing from the polyurethane, visible cracks radiating from the bore, the wheel rocking side-to-side on the axle, or the truck pulling to one side when steering straight. Do not continue operating the truck with damaged wheels as load shift and brake failure can occur, creating a safety hazard.
Q: Is the SU S530-XL-A equivalent to the SU S530-XL?
A: Yes. The SU S530-XL-A is the alternate listing for the SU S530-XL and provides identical dimensions and performance specifications. Both feature the same 3.25 inch by 1.875 inch size, steel core construction, and high-durometer polyurethane with XL3 bonding. Order whichever part number is available from your supplier; they are directly interchangeable replacements.
Q: How should I store unused SU S530-XL-A wheels to prevent damage?
A: Store wheels in a cool, dry location away from direct sunlight, heat sources, and chemical solvents. Keep them indoors at temperatures between 40 and 80 degrees Fahrenheit. Store wheels upright on a rack rather than stacked or laid flat to prevent flat spotting. Do not expose polyurethane to ozone or UV radiation for extended periods. Properly stored wheels maintain full performance for years before installation.
