Blog on Dynamic Balancing Of Rotor by Rokade Group

Rotor Dynamic balancing has a direct effect on the life of any Rotating Machine and productivity. The degree to which a Rotor is out of balance is referred to as imbalance. Rotor imbalance creates force on the bearing assembly, resulting in vibration and heat, which directly affects the Machine performance.

Basically, all machines have some form of residual vibration. Enormous vibration in Rotating Machinery can cause high levels of noise and more importantly, significantly reduce the life of components. So, the ideal way to do would be to remove all causes of vibration and allow the Machine to run smoothly. The process of balancing is the removal or addition of weight to the device, so that this effective mass center approaches the true axis.
