spinning rotor balancing machine

Balancing machines, function, principles and operation

A belt is slung around the rotor and driven by an electric motor to make the rotor spin. The terms soft-bearing and hard-bearing indicate how the rotor is supported on the pedestals. If the rotor support can move freely (soft), the machine is called a soft-bearing balancing machine.

The What, Why, and How of Wheel Balancing

May 25, 2019Wheel balancing—also known as tire balancing—is the process of equalizing the weight of the combined tire and wheel assembly so that it spins smoothly at high speed. Balancing involves putting the wheel/tire assembly on a balancer, which centers the wheel and spins it to determine where the weights should go.
