Overrunning Clutches | Formsprag Clutch

Also known as sprag retainer assemblies, one-way clutches, or freewheels

Formsprag clutches and backstops are the preferred one-way clutch when a purely mechanical solution is required, or as an integral part of a larger hydraulic or electric system. From a basic engineered sprag retainer assembly to a complete custom overrunning clutch system, Formsprag can provide the necessary level of complexity required for the application solution. Free action sprag retainers provide the greatest number of load elements compared to other one-way clutch technologies
