Frequently Asked Questions
Q: What equipment does the NI 40310-SW000 load wheel fit?
A: The NI 40310-SW000 Durarun 95A poly load wheel is designed for UniCarriers 2W7 and WLX Series electric pallet trucks. It cross-references to UK40310-SW000-MIL and replaces 40310-SW000-THO-MIL. Verify your equipment model and bearing bore size match 20 mm before ordering.
Q: What are the physical dimensions and load capacity of the NI 40310-SW000?
A: This load wheel measures 3.25 inches in diameter and 4.50 inches in width, with a 20 mm precision bore. It supports up to 3300 lbs per wheel. The pressed-fit polyurethane tread is molded onto a machined SAE 1045 steel hub.
Q: What material is the NI 40310-SW000 tread and what does 95A durometer mean?
A: The tread is non-marking polyurethane at 95 Shore A durometer (95A hardness). This formulation provides high rebound, wear resistance, and durability for standard warehouse and manufacturing environments. The 95A compound performs well on dry to moderately wet floors.
Q: Is the NI 40310-SW000 a pressed-fit wheel or does it use bearings?
A: The NI 40310-SW000 is a pressed-fit design where the polyurethane tread is molded directly onto the steel hub. This is distinct from bearing-equipped assemblies and is standard for this model series on UniCarriers equipment.
Q: What are the cross-reference part numbers for the NI 40310-SW000?
A: Cross-references include UK40310-SW000-MIL, equivalent to UNI 40310-SW000, and replaces 40310-SW000-THO-MIL. When ordering replacements, confirm the exact part number on your equipment to ensure correct fit and load rating.
