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

Brake and Clutch Friction Lining

Brake and Clutch Friction Lining

Replace the lining in brakes and clutches; also known as friction material

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

Drive Sprockets

Drive Sprockets

Mount directly onto a shaft to transmit rotary motion and torque

Ratchet Gears and Pawls

Ratchet Gears and Pawls

Transmit motion in one direction and stop it in the other

Roller Bearings

Roller Bearings

Support higher loads than ball bearings, but run at lower speeds

Ball Bearings

Create less friction than other bearings for use at high speeds

Electric Motors

Electric Motors

Keep machinery and equipment moving with AC or DC power

Shaft Couplings

Shaft Couplings

Connect two shafts to transfer rotary motion from one to the other
