Frequently Asked Questions
Q: What are the specifications of the SU S9871 load wheel assembly?
A: The SU S9871 features a 3.00 inch outside diameter, 3.66 inch tread width, injection-molded nylon wheel construction, and 20 mm sealed precision ball bearings. The wheel is designed for 20 mm axle compatibility and is engineered for electric lift truck applications.
Q: Is the SU S9871 compatible with a 20 mm axle?
A: Yes. The SU S9871 is specifically engineered with a 20 mm bore and accepts 20 mm axles. Do not force-fit this wheel onto axles of different diameters, as this will damage both the wheel bore and the axle, and will compromise load stability.
Q: What material is the SU S9871 wheel made from?
A: The wheel is constructed from injection-molded nylon compound, which provides good durability and load capacity for standard warehouse and light-duty floor conditions. The nylon tread is quieter than polyurethane but less effective on wet or slippery surfaces.
Q: How do I know if the bearings on my SU S9871 are failing?
A: Symptoms of bearing failure include lateral wheel movement (play), grinding or squealing noise during rotation, increased rolling resistance, or heat at the wheel axle. If you detect these signs, the bearing seals may be compromised. Replace the wheel immediately to prevent load drop.
Q: Can I replace just the bearings in the SU S9871, or must I replace the entire wheel?
A: The SU S9871 uses sealed precision ball bearings that are pressed into the wheel hub. Bearing replacement requires specialized bearing press equipment. In most cases, replacing the entire wheel assembly is more cost-effective and safer than attempting to repress bearings.
Q: Is the SU S9871 equivalent to any other brand load wheel?
A: Cross-reference your OEM part number and wheel specifications. The SU S9871 is compatible with electric lift trucks that accept 3.00 inch OD wheels with 20 mm axles. For specific OEM equivalents, verify the bearing type, bore size, and mounting configuration with your truck documentation or contact our parts team.
