Frequently Asked Questions
Q: What is the SU 9133-XL load wheel assembly and what is XL3 bonding technology?
A: The SU 9133-XL is a professional-grade polyurethane load wheel assembly with 3.25-inch diameter and 3.25-inch width, featuring XL3 bonding technology. XL3 bonding is an engineered adhesive process that bonds Cushothane XL polyurethane to a precision-machined steel core, preventing tread separation under extreme load cycles and adverse surface conditions typical in heavy-duty material handling.
Q: What are the core specifications and material composition of the SU 9133-XL?
A: Core Material: Precision-machined steel core finished for bonding integrity. Tread Material: Cushothane XL polyurethane. Outside Diameter: 3.25 inches (82.55mm). Width: 3.25 inches (82.55mm). Inside Diameter: 1.938 inches. Bore Depth: 0.591 inches. Bore Outside Diameter: 2.0467 inches. Hub Width: 3.25 inches. The precision-machined core ensures consistent bore tolerances and load distribution.
Q: How does the SU 9133-XL compare to standard polyurethane load wheels?
A: The SU 9133-XL uses XL3 bonding to prevent tread separation and delamination that occurs with standard heat-seal or adhesive methods. Standard wheels typically fail after 12 to 18 months in heavy cycle environments. The XL3-bonded SU 9133-XL is rated for extreme load cycles and resists damage from oils, solvents, and rough floors. Expected service life is 24 to 36 months or longer depending on application.
Q: What electric lift truck models is the SU 9133-XL compatible with?
A: The SU 9133-XL is designed for electric pallet jacks and electric lift trucks requiring 3.25 x 3.25-inch load wheels with 1.938-inch inside diameter. It is compatible with many OEM platforms including certain Crown, Toyota, Raymond, and Yale models. Always verify the OEM part number and fitment chart for your specific truck model and serial range before ordering.
Q: How do I diagnose if my load wheel needs replacement?
A: Signs of wheel failure include flat spots, uneven wear, visible cracks in the polyurethane, or chunks of tread missing. If the truck pulls to one side or the wheel does not roll freely, remove the wheel and inspect for bearing damage or tread separation. Spin the wheel by hand; it should rotate smoothly with minimal drag. If polyurethane is peeling or separating from the steel core, replace the wheel immediately to prevent further damage.
Q: Is the SU 9133-XL rated for maximum load and does bore size affect compatibility?
A: The SU 9133-XL inherits the load capacity of your electric lift truck, typically 3,000 to 6,000 pounds for material handling applications. The 1.938-inch inside diameter and 2.0467-inch bore outside diameter are industry-standard load wheel dimensions. Verify your axle journal diameter matches the bore specification; using an oversized or undersized bore will cause wobbling or binding and reduce wheel life.
