Frequently Asked Questions
Q: How does SU S626-XL-A1 compare to SU S626-XL-A?
A: SU S626-XL-A1 and SU S626-XL-A are both load wheel assemblies with identical dimensions: 3.250 inch diameter x 2.875 inch width. The A1 designation typically indicates a revised or updated version. Verify with your parts supplier that both are cross-compatible before substituting; some equipment may require the exact original part number.
Q: Will SU S626-XL-A1 fit trucks that originally had SU S626-XL?
A: Yes, if the truck uses a 25mm bearing bore and 2.875 inch width mounting. SU S626-XL-A1 is a drop-in replacement for SU S626-XL when upgrading to a complete assembly. Always confirm bore depth (0.591 inch) and outside diameter (3.250 inch) match your axle before installation to avoid fitment issues.
Q: What is the specification difference between 82.55mm and 3.250 inch diameter?
A: 82.55mm equals 3.250 inches—this is metric-to-imperial equivalence. SU S626-XL-A1 wheels are manufactured to 82.55mm (or 3.250 inch) diameter. When ordering or cross-referencing wheels, use either measurement; they represent the same wheel specification.
Q: Is SU S626-XL-A1 a non-marking wheel?
A: Yes, SU S626-XL-A1 is constructed from Cushothane XL, a non-marking polyurethane compound designed for use on finished floors. This wheel will not stain or mark polished concrete, epoxy, or vinyl flooring. Verify non-marking capability by testing on a spare floor sample if your facility requires guaranteed floor protection.
Q: What tools do I need to install SU S626-XL-A1?
A: Installation requires a wrench (to fit your axle bolt size, typically 8-10mm), socket set, and lubricating grease. No special tools are needed for the wheel itself. Apply light grease to the axle before sliding the wheel on to prevent friction. Tighten the axle bolt firmly but do not over-torque; over-tightening damages the bearing.
Q: How often should I inspect SU S626-XL-A1 wheels?
A: Inspect wheels monthly in high-use environments. Look for visible cracks, chunks missing from the tread, or uneven wear patterns. Spin each wheel by hand; it should turn smoothly with no grinding noise. If tread depth drops below 0.5 inch or grinding occurs, replace the wheel immediately to prevent equipment damage.
