*Standard Flexible Couplings* The "M" Series Clutch Couplings are for shaft to shaft connection on high speed overrunning applications, such as motor to large fan shaft. Couplings C3 to C7 use Morse silent chain flexible couplings. Couplings C7.5 to Cl0 are Morse Gear Couplings. All couplings are fully sealed for grease lubrication. It is preferred to overrun on clutch shaft, as this permits removal of driving machinery by disconnection at flexible coupling, without driven equipment being stopped. For clutch shaft overrunning select coupling with MG or MO clutch. If shaft diameters dictate that coupling will overrun select MR clutch. Clutch Couplings accommodate up to 1/2 degree angular, and 0.25mm parallel misalignment plus end float as indicated in table.

*Stub Shaft Adaptor* The Morse flanged sub- shaft adaptor is used when it is impractical to mount a sprocket, gear, sheave or other mechanical device directly to the mounting holes of the Morse cam clutch Models 300-1000. The stub shaft diameter is designed to take full advantage of the clutch-torque capacity, but may be turned to smaller diameter to special order, including metric shaft sizes.

Replacement Sprag Clutches PB Sprag Clutch 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.

*HT Sprag Clutch* HT Sprag Clutches are designed for end of shaft applications, being retained on the shaft by a deep groove ball bearing with snap ring in outer race locating in recess dia. The outer race of the clutch is tapped for attaching sprocket, gear or ratchet arm Intended primarily for indexing applications, the clutches can also be used for backstop and overrun applications providing the inner race is overrunning.
