Sprag Clutches PB & HT

PB Sprag Clutches feature precision formed sprags for maximum torque capacities combined with long life. The clutches have an outer race designed to simply attach sprockets, gears or pulleys with a plain bearing to support high radial loads. They are pre-lubricated with grease suitable for temp range -10 to +50°C. Oil lubricated clutches can also be supplied to order (except PB3A). These clutches are suitable for general purpose overrunning and indexing applications.
