Frequently Asked Questions
Q: How does the SU S9135-XL-A1 differ from the SU S9135-XL-A?
A: Both the SU S9135-XL-A1 and SU S9135-XL-A are pre-assembled load wheel kits with identical dimensions (3.25 x 5 inches) and the same Cushothane XL 97A polyurethane compound. The A1 designation indicates a production variant, possibly from a different manufacturing run or equipment configuration. Functionally and dimensionally, they are interchangeable. Verify the bearing type (standard steel or stainless) and your jack model before ordering.
Q: Will the SU S9135-XL-A1 fit my Crown electric pallet jack?
A: The SU S9135-XL-A1 has a 3.25 inch outer diameter, 5 inch width, and 1.938 inch bore, making it compatible with Crown electric pallet jacks and other equipment specifying a 3.25 x 5 load wheel. Check your equipment documentation or the original wheel nameplate to confirm these dimensions match before installation.
Q: What bearing type comes with the SU S9135-XL-A1?
A: The standard SU S9135-XL-A1 is supplied with sealed steel precision bearings (25mm bore). If you require stainless steel bearings for a wash-down or corrosive environment, order the SU S9135-XL-A-SS instead. Do not use the standard A1 assembly in salt spray or high-moisture areas; steel bearings will rust and seize.
Q: Can the SU S9135-XL-A1 be installed without special tools?
A: Yes. The SU S9135-XL-A1 is a ready-to-install assembly. Remove the worn wheel by extracting the axle pin or bolt, slide the new assembly onto the axle, and secure with the pin or bolt. A socket wrench or adjustable wrench is the only tool needed. The wheel should spin freely after installation; if it does not, verify the axle is straight and the pin is fully inserted.
Q: How do I know when to replace the SU S9135-XL-A1?
A: Replace the assembly when you observe flat spots on the wheel surface, visible cracks or chunks missing from the polyurethane, reduced grip causing the jack to slip on smooth floors, or grinding/squealing noise from the bearings when the wheel rotates. Do not continue operating with a damaged wheel; this creates a safety hazard and can damage the jack frame.
Q: Is the SU S9135-XL-A1 equivalent to Hyster or Yale load wheel assemblies?
A: The SU S9135-XL-A1 shares the same outer dimensions (3.25 x 5 inches) as many Hyster and Yale assemblies, but the Cushothane XL 97A compound is Superior-specific. If your equipment originally used a Hyster or Yale wheel, the SU S9135-XL-A1 will mount correctly. However, verify that the bore, core material, and bearing configuration match before substituting; some competitor assemblies use different bearing bores or core configurations.
