Frequently Asked Questions
Q: What is included in the SU S9144-EZ-A wheel assembly?
A: The SU S9144-EZ-A is a complete ready-to-install wheel assembly that includes the 3.25-inch diameter by 4.5-inch width High Traction polyurethane load wheel with EZ compound, steel hub, tapered roller bearings or ball bearings, mounting shaft, and all fastening hardware. The assembly is pre-assembled and tested, requiring only mounting to your equipment bracket.
Q: What equipment models and environments is the SU S9144-EZ-A designed for?
A: The SU S9144-EZ-A is compatible with OL2295, PL123, and 5386 model equipment. It is specifically engineered for wet floors, cold storage freezers, coolers, and general material handling applications where traction on slippery surfaces is critical. Do not use this assembly in standard dry warehouses if traction is not a requirement, as the High Traction compound is optimized for cold and wet performance.
Q: How do I install the SU S9144-EZ-A assembly, and is modification needed?
A: The SU S9144-EZ-A is a direct replacement assembly for compatible equipment. Lift and block your equipment safely. Remove fasteners from the existing wheel assembly and withdraw the old assembly. Insert the SU S9144-EZ-A shaft into the mounting bracket bore and align fastener holes. Thread fasteners by hand, then use a torque wrench to tighten to equipment specifications. No modification of mounting brackets is required if your equipment is within the compatible serial range.
Q: What is the load capacity and duty cycle rating of the SU S9144-EZ-A?
A: The SU S9144-EZ-A assembly is rated for mid-market duty cycles on equipment with a maximum rated capacity of 3000 to 5000 pounds depending on equipment model. It is designed for sustained rolling loads in warehouse, freezer, and wet environment applications. Exceeding your equipment manufacturers rated load capacity will cause premature bearing failure, hub separation, and tread breakdown. High Traction compound performance does not increase weight capacity.
Q: How do I verify the SU S9144-EZ-A is compatible with my equipment?
A: Check your equipment model number against fitment codes OL2295, PL123, or 5386 and verify your equipment serial number falls within the compatible range. Measure your current wheel diameter and width, and confirm they are 3.25 inches diameter by 4.5 inches width. Verify the bore diameter is 1.938 inches. If your equipment model or serial range does not match, do not attempt installation as bearing types and hub designs may differ and cause failure.
Q: What is the expected lifespan of the SU S9144-EZ-A in cold storage?
A: In cold storage with proper maintenance, the SU S9144-EZ-A assembly typically lasts 12 to 24 months before wheel wear or bearing degradation requires replacement. Lifespan is reduced compared to room-temperature use because cold thickens bearing lubricant and thermal cycling loosens fasteners. Inspect the wheel and bearings every 250 operating hours in cold environments. Replace the assembly if the tread becomes hard, if bearings produce grinding noise, or if fasteners cannot be kept tight.
