Uses Cases for Heavy-Duty Clutches

The first units manufactured by Stearns were heavy-duty clutches for paper and steel mills. Offered in both spring engaged (power-off) and electrically engaged (power-on) platforms, Stearns Heavy Duty clutches and brakes provides the heavy lifting and holding in various cement & aggregate and packaging applications including steel mills, motor generator sets, fans, dynamometers, textile processing equipment, steel mill screw-downs, ball mills, rod mills, kilns, and bridge lifts. 

Features

In addition to the size, load and application, Stearns engineers consider torque value, rotation speed, ambient temperature and other requirements during the design process. In applications where DC power is not available, Stearns offers quality, solid-state rectifier controls.

Spring Engaged Clutches vs Electric Engaged Clutches

Electrically actuated industrial clutches, also referred to as electric engaged clutches  and electrically released clutches, also referred to as spring engaged clutches, are similar in that they both transmit or stop torque depending on whether electrical power is turned on or off. The largest difference between spring engaged clutches and electric engaged clutches is electrically engaged clutches or brakes require electrical power to be on in order to transmit torque, while spring engaged clutches or brakes require electrical power to be off in order to transmit torque.
