In 1998, Boston Gear acquired the Centric Clutch Company. Since 1948, Centric Clutch has been manufacturing Centrifugal Clutches for a wide range of industries. Designed as a means to connect power in a drive train with soft start or delay capabilities, Centric's centrifugal clutches were the industry's first overload protection device with repeatable performance.
Capitalising on the need for a dependable and repeatable torque limiter, Centric produced the Trig-O-Matic Overload Release Clutch (Model F and Model S), the original single position, mechanical torque limiting device. Customer requests for a simple cost effective overload device led to the development of the Trig-O-Matic Lite which further solidified the company's position as an industry leader.
Centric revolutionised torque limiting technology with the VariTorque, the first single position pneumatic overload clutch. The VariTorque was designed to meet the specific needs of paper converting machinery where large starting inertias, high production speeds and the possibility of equipment failure is great.
The addition of four Model H Clutches (H1600, H1900, H2000 and PDC), economical ball and roller detent overload clutches and a complete line of friction torque limiters have helped to position the Centric family of products as one of the industry's premier offerings of mechanical overload protection devices.
