Frequently Asked Questions
Q: What are the exact dimensions of the SU S9157 load wheel?
A: The SU S9157 load wheel has an outside diameter of 5.0 inches and a width of 4.12 inches (5.0 x 4.12 or 127.00 x 104.65 millimeters). The inside diameter is 2.125 inches, bore depth is 0.826 inches, and the bore outside diameter is 2.4406 inches. The tread profile is a 3/8 inch radius.
Q: Is the SU S9157 compatible with the SU S9157 XL or SU S9157-EZ variants?
A: The SU S9157, SU S9157 XL, and SU S9157-EZ all share the same 5.0 x 4.12 inch dimensions and bore specifications. However, the XL variant features a steel core with higher durometer polyurethane, and the EZ variant has a high traction polyurethane compound for wet floors and cold storage. Select the variant that matches your application requirements, not the standard S9157 for those environments.
Q: What tread material does the SU S9157 use?
A: The SU S9157 is constructed with polyurethane tread material designed for standard electric lift truck applications. It provides good load support and floor grip in typical warehouse conditions. For wet floors or cold storage, use the SU S9157-EZ variant instead, which features a high traction polyurethane compound.
Q: How long does an SU S9157 wheel typically last?
A: In moderate duty warehouse service, an SU S9157 load wheel typically lasts 18-36 months. Lifespan depends on daily hours of operation, floor conditions, and load consistency. Heavy-duty continuous operations may reduce life to 12-18 months. Replace wheels showing flat spots, tread separation, or chunks missing from the tread.
Q: What should I check if the SU S9157 wheel is not rolling smoothly?
A: First, inspect the wheel for flat spots or debris stuck in the tread. Check the axle connection for looseness or corrosion and ensure the retaining nut is tight but not over-tightened. Spin the wheel by hand - it should rotate freely. If the wheel still does not roll smoothly, the hub bearing may be worn and require replacement. Do not operate the truck until the issue is resolved.
Q: Can the SU S9157 wheel be used on both steer and load axles?
A: The SU S9157 is designed as a load wheel and is typically used on load-bearing axles. Do not use on steer axles, as load wheels and steer wheels have different tread profiles and load ratings. Always verify your electric lift truck documentation to confirm wheel placement. Using the wrong wheel type can cause uneven wear and handling problems.
