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. EZ does not refer to installation difficulty. This compound formula provides improved grip and braking performance in food, beverage, and refrigerated warehouse environments.
Q: What are the dimensions of the SU S9133-EZ load wheel?
A: The SU S9133-EZ measures 3.250 inches outer diameter by 3.250 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 3.250 inches.
Q: Which electric pallet jacks 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, Raymond, and Yale models with 3.25-inch wheel assemblies. 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. Use standard polyurethane wheels in dry indoor warehouses.
Q: How do I replace the SU S9133-EZ wheel on my electric pallet jack?
A: Lift the truck clear of the load. Remove the axle bolt or pin and slide the worn wheel off the shaft. Press the SU S9133-EZ onto the axle, aligning the hub bore with the shaft diameter. Ensure bearings seat fully and the wheel rotates without drag. Reinstall the axle fastener and verify smooth rotation before operating.
Q: What is the 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.
