AD Piston Ring has been producing seals and rings for servo motor repairs and maintenance for hydroelectric dam operators for more that 100 years. We are experts in large seals and a leading provider of dam servo motor overall and maintenance seal and ring maintenance applications. Many servo motor refurbishments and repairs on dams and hydroelectric plants utilize our bronze material and well as our Shurseal joint rings. Servo motors, because they are used in such precise applications, need to be carefully maintained and calibrated to ensure optimal working conditions. You don’t want to cut any corners when working with a servo motor, so you need to ensure that you have all the correct parts for the work you are doing.

Servo motor piston rings are designed specifically for use in these unique machines. Because servo motors are generally very large, the rings need to be specifically shaped to fit in these precise mechanisms. In addition, we also manufacture for other applications as, servo motors are often used in remote-control robotics, from toy cars to industrial manufacturing robots.
