Frequently Asked Questions
Q: What is the exact wheel diameter and width of the SU 9135-A load wheel assembly?
A: The SU 9135-A has an outside diameter of 3.25 inches (82.55mm) and a width of 5 inches (127.00mm) side to side. The inside diameter is 1.938 inches and the bore depth is 0.591 inches. This is a standard load wheel size for most electric pallet trucks and lift platforms. Verify your current wheel dimensions before ordering to ensure direct fit.
Q: Is the SU 9135-A compatible with my electric pallet jack model?
A: The SU 9135-A is designed for electric lift truck and pallet jack applications with a 3.25 x 5 inch wheel mounting pattern. Before confirming compatibility, check your equipment manual or existing wheel assembly for matching dimensions and bore specifications. The bore outside diameter is 2.0467 inches and hub width is 5 inches. If your jack currently runs 3.25 x 5 wheels, this assembly will fit. Cross-reference your equipment model number and serial range to be certain.
Q: What material is the SU 9135-A wheel made from and how long will it last?
A: The SU 9135-A uses Cushothane XL compound, a polyurethane material designed for durability and low rolling resistance. Expected lifespan depends on load, floor surface, and usage frequency. On smooth warehouse floors with standard pallet loads, most units last 2 to 4 years of continuous operation. Abrasive outdoor surfaces or overload conditions will shorten life significantly. Inspect wheels quarterly for flat spots, cracks, or uneven wear. Replace the assembly when tread depth falls below 0.25 inches or visible damage appears.
Q: Does the SU 9135-A come with bearings installed?
A: The SU 9135-A is a load wheel assembly specification but does not explicitly state whether sealed precision bearings are factory-installed. Before installation, verify the product documentation or contact the supplier to confirm if bearings are included or must be purchased separately. If bearings are not pre-installed, you will need to source compatible 1.938 inch inner diameter sealed bearings. Do not install the wheel without proper bearing support, as this will cause rapid failure and unsafe operation.
Q: What is the hub width and bore depth of the SU 9135-A wheel?
A: The hub width is 5 inches and the bore depth is 0.591 inches. These dimensions ensure the wheel seats correctly on the axle mounting hardware. The bore outside diameter is 2.0467 inches. When installing, ensure your axle shaft diameter matches the inside bore of 1.938 inches and that the mounting hardware clears the bore depth specification. Misalignment or incorrect bore sizing will result in wobbling, noise, and premature wear.
