Electric Motor Bearing Balancing & Repair 

Louis Allis' specialty electric motor repair and manufacturing equipment are top-of-the-line. In this video, one of our Project Managers discusses a piece of equipment we use every day, a hard bearing balance machine. A bearing balancing machine provides crucial information on the balance of a large electric motor bearings. If this crucial piece is out of spec, motors can perform poorly which can lead to catastrophic engine failure. This machine typically balances to a G2.5 specification which is defined by a specific equation using the bearing weight, rotational speed, and center of gravity, and can handle weights up to 15,000 lbs. Our bearing balancing equipment can surpass the industry standard of G2.5 for electric motors, and balance to a G1 specification for special circumstances. 

Louis Allis equipment and machines are inspected and calibrated annually to make sure they stay in prime working condition to continue repairing and manufacturing the world's best specialty electric motors.
