Frequently Asked Questions
Q: What does the -EZ designation mean on the SU S9133-EZ?
A: The -EZ suffix indicates a high-traction polyurethane compound engineered for wet floors, cold storage, and slip-prone surfaces. This compound formula provides improved grip and braking performance in food, beverage, and refrigerated warehouse environments where standard wheels lose traction.
Q: What are the dimensions of the SU S9133-EZ load wheel?
A: The SU S9133-EZ measures 3.25 inches outer diameter by 3.25 inches tread width. The inner bore is 1.938 inches with a bore depth of 0.591 inches and a bore outside diameter of 2.0467 inches. Total hub width matches the tread width at 3.25 inches.
Q: Which electric pallet jacks and lift trucks use the SU S9133-EZ wheel?
A: The SU S9133-EZ is compatible with electric pallet jacks and lift trucks that use 3.25-inch diameter load wheels with the specified bore configuration. Common brands include Crown, Toyota, Yale, Hyster, and Raymond models with 3.25-inch wheel assemblies. Always confirm bearing ID and hub profile against your equipment specifications before ordering.
Q: Why should I use the SU S9133-EZ in cold storage or wet conditions?
A: The EZ high-traction compound maintains grip on wet, oily, and cold floors where standard polyurethane loses traction. This reduces wheel slip, improves braking response, and minimizes load drift in freezer warehouses and wash-down environments. Standard polyurethane wheels are recommended for dry indoor warehouses.
Q: What is the expected service life of the SU S9133-EZ in cold storage?
A: In cold storage and wet conditions, expect 12 to 24 months of service depending on cycle frequency and floor cleanliness. EZ compound degrades faster in acidic wash waters and salt residue. Inspect wheels monthly in harsh environments. Replace if tread softens, discolors, or shows permanent deformation from load.
Q: How should the SU S9133-EZ be stored before use?
A: Store wheels in a cool, dry location away from direct sunlight, ozone sources, and extreme heat. Keep away from oils, solvents, and chemicals that can degrade polyurethane. Store vertically or lay flat on a clean surface. Avoid prolonged storage in subfreezing temperatures, which may cause the compound to become brittle.
