Frequently Asked Questions
Q: What are the dimensions and specifications of the SU S126-A polyurethane load wheel?
A: The SU S126-A is a polyurethane load wheel assembly with a 3.5 inch outside diameter and 1.56 inch tread width. The tread is made from polyurethane compound and the hub is high carbon steel. It is designed for intermittent duty cycles in material handling environments including electric pallet jacks and lift trucks from major OEM manufacturers.
Q: Which electric pallet jacks and lift trucks does the SU S126-A fit?
A: The SU S126-A is compatible with electric pallet jacks and lift trucks from Crown, Toyota, Raymond, Yale, Hyster, and other OEM brands that use 3.5 inch diameter load wheels with 1.56 inch tread width. Verify the bore diameter and axle mounting type on your equipment match this assembly. Cross-reference your pallet jack or lift truck manual with the SU S126-A specifications to confirm fitment.
Q: How do I replace a worn load wheel with the SU S126-A?
A: If the wheel is bolt-mounted, remove fasteners and slide the worn wheel off the axle. Align the SU S126-A with the axle and hub holes, then reinstall fasteners and torque to manufacturer specifications. If the wheel is press-fit onto the axle, use an arbor press to seat it fully and evenly. Test wheel rotation to confirm smooth operation and verify no wobbling before returning the equipment to service.
Q: What load capacity and duty cycle is the SU S126-A designed for?
A: The SU S126-A is engineered for intermittent duty cycles in material handling environments, typical of warehouse and retail pallet jack and lift truck operations. Consult your equipment documentation for the specific load center and rated capacity. Do not exceed rated load limits, as overloading accelerates tread wear and bearing degradation.
Q: When is it time to replace the SU S126-A load wheel?
A: Replace the SU S126-A when tread wear reaches 50 percent of original depth, visible cracks or chunks of polyurethane appear, the wheel wobbles or is loose on the axle, or bearing noise increases during operation. Perform monthly visual inspections. High-use environments may require quarterly or more frequent replacement depending on usage intensity.
Q: Is the SU S126-A suitable for wet floor or cold storage operations?
A: The polyurethane compound on the SU S126-A is optimized for standard dry warehouse conditions. If your pallet jack or lift truck operates in wet floor or cold storage areas, ask about load wheel options with High Traction polyurethane formulations designed for improved grip and reduced slipping in wet and cold environments.
