The Internal Balancer is a preferred choice by many European grinding machine builders. This balancer type is designed to fit inside the grinding spindle, in a bore supplied by the machine builder. The balance weights are located under the wheel, eliminating any possible lateral coupled forces on the spindle. Placement of the Balancer inside the spindle minimizes possible interferences between the Balancer and other machine components.
The SBS Internal Balancers feature a balance compensation range of 100 – 7,000 g•cm or larger and can operate from 300 – 13,000 rpm.
