Bearings are easily affected by shock forces. Depending on the size of the bearing, a shock force from a 100 gram weight at 4mm away could cause brinelling. Brinelling could also occur when bearings are automatically press-fitted to a rotor shaft, if the shaft and bearing bore are not kept accurately in line.
A typical example of shock causing brinelling is when motors are placed on a conveyor belt. As the motors moved through the conveyor, the movement causes the motors to hit the iron plate underneath the conveyor, resulting in shock which causes brinelling to the bearing. Holes made to the iron plate prevent this type of shock force to be generated.
