Frequently Asked Questions
Q: What are the specifications of the SU S2377 polyurethane load wheel?
A: The SU S2377 features a nominal diameter of 3 inches and width of 3.66 inches. It has a steel hub, red polyurethane tread for abrasion resistance, and integrates a 20 mm sealed precision bearing. This configuration provides non-marking traction on finished floors.
Q: Is the SU S2377 equivalent to the SU S2377-A?
A: SU S2377 is the wheel component with bearing. SU S2377-A is the complete load wheel assembly and supersedes SU S2377 for some equipment applications. Check your lift truck manual or OEM documentation to confirm which part number applies to your specific model.
Q: What floor types is the SU S2377 suitable for?
A: The red polyurethane tread is non-marking and is ideal for polished concrete, tile, sealed wood, and clean warehouse floors. It does not mark or stain floor surfaces. Avoid using this wheel on outdoor surfaces, loose gravel, or rough concrete where the tread may deteriorate prematurely.
Q: How do I install the SU S2377 onto my lift truck axle?
A: Verify your axle diameter is 20 mm. Slide the wheel onto the axle, ensuring the bearing seats fully. Secure with the retaining clip, snap ring, or cotter pin as specified in your equipment manual. The wheel should rotate freely with no lateral play after installation.
Q: What maintenance does the SU S2377 sealed bearing require?
A: The 20 mm sealed precision bearing is maintenance-free and does not require lubrication. Inspect the bearing monthly by spinning the wheel by hand—it should rotate smoothly and freely. If the wheel wobbles, does not spin, or makes grinding noise, the bearing has failed and the assembly must be replaced.
Q: How long does the polyurethane tread typically last?
A: Tread lifespan depends on usage intensity, floor type, and load weight. Light-duty indoor use may provide 2-3 years of service. Heavy-use applications may require replacement within 12-18 months. Inspect tread depth regularly. Replace when tread is visibly worn smooth or when flat spots develop.
