Frequently Asked Questions
Q: What are the cross-reference part numbers for the SU S163-XL?
A: The SU S163-XL is equivalent to SUS163-XL, SUS163-XL-A1, SUS163XLA1, and S163XLA1. All of these numbers refer to the same 97A polyurethane load wheel assembly for Superior-brand lift trucks. When ordering, use any of these part numbers interchangeably, but always verify SKU on the invoice to confirm correct shipment.
Q: What is the durometer rating and material of the SU S163-XL wheel?
A: The SU S163-XL wheel is 97A durometer, made of Cushothane XL polyurethane compound. This is a high-durometer, hard compound designed for heavy-duty service and superior wear resistance on industrial floors. The 97A rating is suitable for high-load applications and long-distance travel.
Q: What are the exact dimensions of the SU S163-XL wheel?
A: Outside diameter: 3.25 inches (82.55 mm). Inside diameter: 1.938 inches. Width side to side: 4.5 inches (114.30 mm). Tread profile: angle cut. Bore depth: 0.71 inches. Hub width: 4.5 inches. Bore outside diameter: 2.0467 inches. These dimensions are factory specifications; verify against your original wheel before ordering.
Q: Is the SU S163-XL pre-assembled with bearing and axle?
A: Yes. The SU S163-XL is a complete wheel assembly pre-assembled with bearing and axle. It is designed as a direct drop-in replacement for Superior-brand electric lift trucks. Remove the old assembly and install the new one using the same fasteners and mounting points.
Q: What lift truck brands and models are compatible with the SU S163-XL?
A: The SU S163-XL is confirmed compatible with Superior-brand electric lift trucks. Cross-reference numbers (SUS163-XL, S163XLA1) also indicate use in Pallet Jackson material handling equipment. For other brands or models, check the truck manual or contact technical support with your model number. Using an incompatible assembly may result in poor fit or safety issues.
Q: When should I replace the SU S163-XL assembly instead of just the wheel?
A: Replace the entire SU S163-XL assembly if the bearing shows play, is difficult to turn, or spins with resistance; if the axle is bent or corroded; or if both wheel and bearing are worn. Replacing the entire pre-assembled unit is faster and safer than attempting to separate and rebuild components. A worn bearing will quickly damage a new wheel, so address bearing wear immediately.
