Frequently Asked Questions
Q: What distinguishes the SU S9163-XL-A assembly from the standard SU S9163-XL wheel?
A: The SU S9163-XL-A is a complete wheel assembly that includes an aluminum finned hub with HeatSink technology, whereas the SU S9163-XL is the wheel only. The assembly is pre-mounted and ready to install, designed specifically for high duty cycle applications where rapid heat dissipation prevents wheel degradation from thermal stress.
Q: What are the dimensions and material specifications of the SU S9163-XL-A?
A: The SU S9163-XL-A measures 6.000 inches outside diameter by 4.125 inches width with a 2.947 inch bore diameter. The Cushothane XL tread has a 97 Shore A durometer hardness, and the hub features aluminum construction with finned HeatSink technology. Bore depth is 0.827 inches with a 3.1471 inch bore outside diameter.
Q: Why is the HeatSink technology important in the SU S9163-XL-A hub?
A: Electric lift trucks operating at high duty cycles generate significant friction heat at the wheel and bearing interface. The aluminum finned hub increases surface area for heat dissipation, keeping the wheel and hub cooler during extended use. This reduces polyurethane degradation and extends both wheel and bearing lifespan in demanding applications.
Q: What equipment is the SU S9163-XL-A designed to fit?
A: This assembly is designed for electric lift truck load wheel positions in equipment from manufacturers such as Crown, Toyota, Raymond, Yale, and Hyster. Verify that your equipment mount point accommodates the aluminum finned hub geometry and that bore specifications match 2.947 inches before ordering.
Q: Is the SU S9163-XL-A assembly ready to install, or does it require additional preparation?
A: The SU S9163-XL-A is a complete pre-assembled wheel and hub unit. Before installation, inspect the bore and bearing surfaces for damage, ensure the equipment axle is clean and free of debris, and confirm that the bore diameter fits within tolerance. Apply appropriate bearing lubricant per your equipment manufacturer specifications before mounting.
