Frequently Asked Questions
Q: What is the difference between the SU S248 and SU S248-A?
A: The SU S248-A is a load wheel assembly featuring a 95A durometer Durarun polyurethane tread bonded to a precision-machined steel core. The SU S248 uses Cushothane EZ material. The SU S248-A tread compound is more durable and offers better performance in heavy-load and long-run applications.
Q: What are the full specifications of the SU S248-A?
A: SU S248-A specifications are: 3.25 inch outside diameter by 6.00 inch width, 1.875 inch inside diameter, 0.912 inch bore depth, 6 inch hub width. Tread compound is 95A durometer Durarun polyurethane bonded to a steel core with synthetic backing. Material listed as Cushothane EZ overall assembly.
Q: Is the SU S248-A a direct equivalent to OEM SU S248-A?
A: Yes. The SU S248-A is designed as a replacement assembly for the OEM part number SU S248-A. Confirm your truck or lift equipment currently uses this exact part number before ordering.
Q: What does 95A durometer rating mean?
A: The 95A durometer measurement indicates polyurethane hardness on the Shore A scale. A 95A rating is medium-hard, providing good durability and load-carrying capacity while maintaining reasonable floor grip and wear resistance for electric lift truck service.
Q: What is the advantage of the bonded steel core design?
A: The precision-machined steel core provides structural rigidity and load distribution, preventing wheel deflection under heavy loads. The bonded polyurethane tread offers wear resistance and grip. This design extends wheel life in demanding industrial environments compared to solid polyurethane wheels.
Q: How do I install the SU S248-A on my lift truck?
A: Remove the axle clip or cotter pin and slide the worn wheel off. Slide the SU S248-A onto the axle until the bearing bore seats fully on the axle. The bore inside diameter is 1.875 inches. Secure with the axle clip, cotter pin, or fastener. Do not force the wheel onto the axle. If it does not slide smoothly, verify axle diameter and cleanliness.
