Dynamic Balancing Training - CLASS IS FULL

Course 4009

This two-day course is for all managers, engineers and technicians whose duties entail improving the reliability of rotating machines. When the course is concluded, the participant will be able to develop an effective method for the dynamic balancing of various plant rotors.

Mass imbalance is a primary cause of failure in rotary machinery. Every time a machine shaft makes a revolution, unbalance forces are transmitted through the bearings and machine structure, causing premature wear and shortening equipment life. Dynamic balancing is one of the key components for a predictive maintenance program in the plant.
