Power Transmission

Torque Limiters

Torque Limiters

Keep torque at or below a set limit to control tension or braking or protect machinery from overload

Clutches

Start and stop the transmission of power to machinery

Brakes

Control how much and how quickly your drive system slows down

Clutch/Brakes

Control when to transmit power with a clutch and when to hold a load in place with a brake

Shear Couplings

Shear Couplings

Sever the connection between shafts when there's too much torque to protect parts from breaking
