Centrifugal Clutches

In 1998, Boston Gear acquired the Centric Clutch Company. Since 1948, Centric Clutch has been manufacturing Centrifugal Clutches for a wide range of industries.

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.

Centric revolutionised torque limiting technology with the VariTorque, the first single position pneumatic overload clutch and the four Model H Clutches (H1600, H1900, H2000 and PDC).

Ameridrive Couplings

Ameridrives Couplings Products began manufacturing in 1928 as the Mechanical Drives Division of Zurn Industries. Through the years Coupling Products have pioneered many improvements to keep in step with changing technologies of power transmission equipment.

The basic gear coupling design was the stepping stone for the development of reliable and economical Amerigear Mill Spindles. Coupling Products introduced the Ameriflex non-lubricated diaphragm coupling in 1971 for the increased demands of high performance turbo machinery equipment.
