Frequently Asked Questions
Q: What does the EZ designation mean on the SU S9157-EZ wheel?
A: The EZ designation indicates a high traction polyurethane compound formulated for material handling equipment in wet floors and cold storage environments. EZ does NOT mean easy installation or easy replacement. It refers to the tread material compound that provides superior grip on slippery and low-temperature surfaces where standard polyurethane wheels lose traction.
Q: What are the dimensional specifications for the SU S9157-EZ?
A: The SU S9157-EZ has an outside diameter of 5.0 inches and a width of 4.12 inches (5.0 x 4.12 or 127 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. These dimensions match the standard SU S9157 bore specifications.
Q: When should I use the SU S9157-EZ instead of the standard SU S9157?
A: Use the SU S9157-EZ when your electric lift truck operates in wet floors, freezer units, cold storage, or areas where moisture is present. The high traction polyurethane compound provides enhanced grip in these conditions. For standard dry warehouse service, the standard SU S9157 is adequate and may be more cost-effective. Using the wrong wheel type can result in slipping and safety hazards.
Q: Is the SU S9157-EZ compatible with trucks that previously used standard SU S9157 wheels?
A: Yes, the SU S9157-EZ is a direct replacement for the standard SU S9157 in terms of bore diameter and dimensions (5.0 x 4.12 inches, 2.441 inch bore). Remove the old wheel and install the SU S9157-EZ using the same retaining hardware and procedure. The only difference is the high traction tread compound, which performs better in wet and cold conditions.
Q: How long does the SU S9157-EZ wheel last in cold storage or wet environments?
A: In cold storage or wet floor service, the SU S9157-EZ typically lasts 2-4 years, depending on daily operating hours and environmental severity. The high traction compound may wear slightly faster than standard polyurethane due to the increased grip required. Inspect wheels regularly and replace if tread is worn flat, separation occurs, or chunks of material are missing.
Q: What should I do if the SU S9157-EZ wheel loses traction or feels slippery?
A: If the SU S9157-EZ wheel loses grip on wet or cold floors, first clean the tread thoroughly to remove ice, grease, or contaminants. Inspect for worn flat spots or tread damage. If tread depth is significantly reduced or separation is visible, replace the wheel immediately. Continued operation on slippery wheels creates safety hazards and increases accident risk.
