Product description

The 40mm Stub Shaft is a heavy-duty mounting component designed for Snap-On wheel balancers, providing a stable and accurate platform for mounting wheel assemblies during the balancing process. This 40mm diameter shaft is precision-ground to ensure minimal runout, which is critical for achieving the high-precision balance required by modern automotive standards. The shaft is heat-treated for enhanced surface hardness, allowing it to support the weight of heavy wheels without bending or developing surface indentations. It is compatible with a wide range of standard 40mm adapters and cones. Regular inspection and replacement of the stub shaft are necessary to ensure that your balancer remains within calibration and provides the repeatable accuracy your customers expect.
