Frequently Asked Questions
Q: What are the exact specifications of the SU S458 poly load wheel?
A: The SU S458 is a polyurethane load wheel with 5.000 inch outside diameter and 3.875 inch width (127.00mm x 98.42mm metric). Outside diameter is 5 inches, inside diameter (bore) is 2.188 inches, and width side to side is 3.875 inches. Tread profile is a 3/8 inch radius. Bore depth is 0.67 inches and bore outside diameter is 2.4384 inches. Material is Cushothane XL polyurethane.
Q: Is the SU S458 wheel compatible with the SU S458-A assembly, or do I need the complete assembly?
A: The SU S458 is the wheel only. The SU S458-A is the complete wheel assembly including hardware and bearings. If you need a wheel replacement and your existing assembly is still serviceable, order the SU S458 wheel. If your bearing is damaged or the assembly is broken, order the SU S458-A assembly as a complete replacement unit.
Q: Can I install the SU S458 wheel on different lift truck models?
A: The SU S458 can only be used on electric lift trucks with a 2.188 inch bore diameter and 3.875 inch width spacing. Verify your truck axle bore diameter by measuring with calipers before ordering. If your truck requires a different bore or width, the wheel will not fit. Forcing a mismatched wheel onto an axle will damage both the wheel and axle shaft.
Q: What is the hardness rating and load capacity of the SU S458 wheel?
A: The SU S458 is manufactured from Cushothane XL polyurethane, which typically provides 95-97A Shore hardness for durability in industrial lift truck applications. Load capacity depends on the truck model and wheel position. Always verify load limits in your truck manual. Exceeding the rating causes tread separation, cracking, and axle bearing failure.
Q: How often should I replace the SU S458 wheel during the life of my lift truck?
A: Lifespan depends on load, usage hours, and environmental conditions. Inspect the wheel every 250 operating hours for wear. Most polyurethane wheels require replacement between 1,500 and 3,000 hours if operated under normal load conditions. Heavy or overloaded trucks reduce wheel life. Replace immediately if the wheel develops flats, cracks, or irregular wear patterns.
