Frequently Asked Questions
Q: What equipment does the SU S9137 load wheel fit?
A: The SU S9137 is a Superior load wheel designed for electric pallet jacks and material handling equipment. Without access to the original OEM documentation, you must verify the wheel dimensions (diameter and width) against your equipment to confirm compatibility. Check your jack nameplate or the existing wheel for size specifications before ordering.
Q: Is the SU S9137 a complete assembly or a wheel only?
A: The SU S9137 is listed as a load wheel. Verify with Superior Industries or your supplier whether this is a bare wheel or a pre-assembled unit with bearings installed. This distinction determines whether you need additional components (axles, bearings) for installation or if the wheel is plug-and-play ready.
Q: What is the recommended replacement interval for the SU S9137?
A: Replacement interval depends on duty cycle and environment. In typical warehouse use, inspect the wheel monthly for wear, flat spots, or loss of grip. Most load wheels require replacement every 18-24 months depending on hours of operation and floor conditions. Replace immediately if cracks, chunks, or flat spots appear on the wheel surface.
Q: How do I install the SU S9137 wheel on my pallet jack?
A: Installation depends on whether the SU S9137 is a bare wheel or assembly. If bare, you will need to bond the wheel to a steel core and install bearings, or source a pre-assembled core. If it is a pre-assembled unit, remove your old wheel by extracting the axle pin, slide the SU S9137 onto the axle, and secure the pin. Consult your equipment manual or Superior documentation for specific bore size and mounting specifications.
Q: Can the SU S9137 be substituted for other Superior load wheel models?
A: The SU S9137 and other Superior models (such as S9135-XL variants) may share similar dimensions but are not automatically interchangeable. Verify the diameter, width, bore size, and bearing configuration of the S9137 against the specifications of the wheel you are replacing. Mismatched dimensions or bearing bores will result in installation failure or poor performance.
Q: What maintenance is required to extend the life of the SU S9137?
A: Weekly: clean the wheel with a damp cloth to remove debris and buildup. Monthly: check that the wheel rotates freely with no grinding noise or resistance. Do not use high-pressure washers or harsh solvents that degrade the polyurethane bond. If the wheel develops flat spots or begins to slip, replacement is the only option; repair is not possible.
