Frequently Asked Questions
Q: What components are included in the SU S9144-A assembly?
A: The SU S9144-A is a complete wheel assembly that includes the 3.25-inch diameter by 4.5-inch width polyurethane load wheel, steel hub, tapered roller bearings or ball bearings depending on equipment model, mounting shaft, and all fastening hardware. This assembly is ready to mount directly to your equipment without additional components or modification.
Q: Is the SU S9144-A assembly plug-and-play or does it require modification?
A: The SU S9144-A is designed as a direct replacement assembly for OL2295, PL123, and 5386 model equipment. No modification is required if you are replacing an existing wheel assembly on compatible equipment. Verify that the mounting bracket bore diameter and shaft configuration match your equipment before installation. If the mounting brackets are damaged or have different bore sizes, brackets may need adjustment or replacement.
Q: What tools and safety precautions are needed to install the SU S9144-A?
A: You will need a socket wrench or adjustable wrench to remove and install fasteners, a wheel removal tool if the wheel is press-fitted, and a torque wrench to ensure fasteners are tightened to equipment specifications. Always lift and block the equipment safely before removing wheels. Never work under equipment supported only by a jack. Ensure all fasteners are tightened to prevent wheel detachment during operation.
Q: What is the load capacity and duty cycle for the SU S9144-A assembly?
A: The SU S9144-A assembly is rated for mid-market duty cycles on equipment with a maximum rated capacity of 3000 to 5000 pounds, depending on the specific equipment model. The wheel itself is designed to support sustained rolling loads in warehouse and light industrial environments. Do not exceed your equipment manufacturers rated capacity, as overloading will cause premature bearing failure, hub separation, and tread breakdown.
Q: How do I verify the SU S9144-A fits my current equipment?
A: Check your equipment model number against the fitment codes OL2295, PL123, or 5386. Measure the 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 and the mounting bracket configuration matches. If your equipment serial number falls outside the compatible range, 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-A assembly in typical warehouse use?
A: With proper maintenance and normal mid-market duty use, the SU S9144-A assembly typically lasts 18 to 36 months before wheel tread wear or bearing wear requires replacement. Lifespan depends on operating hours, floor surface type, load consistency, and maintenance frequency. Heavy dust or water exposure will reduce bearing life. Inspect bearings and tread every 500 operating hours to plan replacement before failure occurs.
