Frequently Asked Questions
Q: What are the dimensions of the SU S9133-A load wheel assembly?
A: The SU S9133-A has an outer diameter of 3.250 inches (82.55 mm) and a width of 3.250 inches (82.55 mm). The bore diameter is 1.938 inches with a bore outside diameter of 2.0467 inches. The bore depth is 0.591 inches, and the hub width is 3.25 inches. These dimensions are critical for fitment verification on your specific electric pallet jack model.
Q: What material is the SU S9133-A wheel made from?
A: The SU S9133-A is constructed from Cushothane XL, a high-durometer polyurethane elastomer designed for load-carrying duty. Cushothane XL provides superior floor grip, impact resistance, and wear life compared to standard polyurethane. It is ideal for repetitive lift and lower cycles in warehouse environments where load wheel stability is critical.
Q: Is the SU S9133-A a complete assembly or just the wheel?
A: The SU S9133-A is a load wheel assembly, meaning it includes the wheel hub, bearing pocket, and mounting interface. Verify whether your equipment requires the complete assembly or if you need only the wheel portion. Do not assume the assembly includes a preinstalled bearing or axle unless specified in the full product specifications.
Q: How do I diagnose a failing SU S9133-A load wheel?
A: Warning signs include uneven jack lift height, lateral drift during travel, audible grinding or squeaking, visible cracks or flat spots on the wheel, or separation of the wheel tread from the core. Rotate the wheel by hand and listen for bearing roughness. If the wheel does not spin freely or shows play on the axle, replace the assembly immediately to prevent load shift and equipment damage.
Q: What is the expected service life of the SU S9133-A in typical warehouse use?
A: In moderate-duty warehouse service with regular maintenance, the Cushothane XL wheel typically provides 18 to 36 months of reliable performance before replacement is needed. High-cycle operations (8 or more hours per day with heavy loads) may shorten service life to 12 to 18 months. Inspect wheels every 3 months for wear, and replace any showing more than 0.125 inch of tread loss.
Q: Can I use the SU S9133-A as a replacement for other aftermarket or OEM load wheels?
A: The SU S9133-A is compatible only with electric pallet jack models that specify this exact bore diameter (1.938 inch), width (3.25 inch), and hub configuration. Before substituting any load wheel, confirm fitment with your equipment OEM or consult the assembly diagram. Incorrect wheel selection will cause binding, misalignment, and premature failure of the lift mechanism.
