Product description

This Snap-On chuck assembly rod is a central structural component of the wheel clamping mechanism on tire changers and balancers. It provides the linear force and alignment necessary for the chuck jaws to grip the wheel rim securely during service. Precision-machined from high-strength alloy steel, the rod is designed to withstand the immense tensile and compressive loads generated by pneumatic or mechanical clamping systems. Its smooth surface finish ensures low friction during actuation, while its dimensional accuracy guarantees a direct fit within the chuck body. A bent or worn rod can lead to improper wheel centering or slipping, which can cause damage to the rim and inaccurate results during balancing or tire mounting. Replacing the rod is an essential maintenance step to ensure that the chuck assembly maintains its original grip strength and alignment accuracy for safe wheel service.
