Power Transmission

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

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

Electric Motors

Electric Motors

Keep machinery and equipment moving with AC or DC power

Chain and Belt Torque Limiters

Chain and Belt Torque Limiters

Prevent chain or belt damage from overloading; loads above the set torque trigger a stop
