Product Solutions
Bi-Directional Backstops & Clutches
Formsprag Bi-Directional Clutches & Backstops are mechanical clutches designed to transmit torque in both directions but restrain feedback torque of the driven load from rotating the output shaft in either direction. These clutches can transmit torque in either rotational direction while automatically providing a holding brake function when the driving torque is stopped. This makes them essential for applications where bi-directional control and reliable stopping are required.
Electromagnetic Clutches & Brakes
The Formsprag portfolio of Electromagnetic Clutches and Brakes is crafted for optimal energy efficiency, ensuring minimal power consumption without sacrificing performance. These compact and powerful products provide high torque density for their size and weight. Our comprehensive range includes power-on and power-off brakes, tooth clutches, friction clutches, and permanent magnet clutches and brakes.
Overrunning Sprag Clutches
Formsprag Sprag Overrunning Clutches are engineered to provide drive in one direction while allowing "freewheeling" in the opposite direction. These clutches are perfect for applications requiring high overrunning speeds and reliable backstopping capabilities. Their robust design ensures smooth operation and dependable performance in demanding environments.
