Frequently Asked Questions
Q: Is the SU S458-XL-A compatible with Superior SUS458-XL jacks?
A: Yes. The SU S458-XL-A is the direct equivalent to Superior SUS458-XL. Both are 5 inch diameter by 3.875 inch width load wheels with 97A Shore hardness polyurethane tread and steel core. Cross-reference with confidence for drop-in replacement on any jack rated for 5 x 3.875 wheels.
Q: What is the bore diameter and how do I verify fit before installation?
A: The SU S458-XL-A has a 2.188 inch inside diameter bore. Measure the axle shaft diameter on your jack before ordering. The wheel must slide freely onto the shaft with minimal play. If your axle is 2.125 inch or 2.250 inch, this wheel will not fit without adapter sleeves. Always verify the bore dimension matches your jack specifications.
Q: When should I replace the SU S458-XL-A wheel?
A: Replace when tread depth is less than 1/8 inch, when flat spots or chunks are visible, or when the wheel no longer maintains load capacity under rated load. 97A hardness wheels typically last 2-4 years in regular warehouse use. If wheels slip on smooth floors under load, replacement is needed immediately.
Q: Can I use SU S458-XL-A wheels on an electric pallet jack rated for manual operation?
A: Yes, SU S458-XL-A wheels are compatible with both manual and electric lift trucks. The polyurethane tread and steel core support the load equally. However, verify that your jack frame and bearings are rated for the intended load. Do not exceed the jack manufacturers rated load capacity.
Q: What is the metric equivalent size for SU S458-XL-A?
A: The SU S458-XL-A measures 127.00 millimeters diameter by 98.42 millimeters width. These metric dimensions are equivalent to 5 inches by 3.875 inches. When ordering replacements from metric-based suppliers, reference both inch and millimeter measurements to ensure correct part.
Q: Is bearing replacement required during wheel installation?
A: Bearing replacement is not required for wheel installation. The SU S458-XL-A is a wheel assembly with a precision machined steel core. Inspect the axle shaft and existing bearings for wear, scoring, or discoloration before sliding the new wheel on. If the axle is damaged or bearings are worn, replace those components first to ensure proper wheel operation.
