Model SXT
Model SXT fits a range of motor and reducer shafts.
Model SXT is designed to fit on the standard shaft extension of motors and reducers. It provides bearing support for overhung or side loads of chain or belt drives. The standard clutch is available with either a #35 pitch 18 tooth sprocket, 2.2 pitch diameter A Section pulley for ready use, or a plain shaft for your pulley, gear, or sprocket. 

These clutches run in any position, run in either direction, need no lubrication, disengage at a preset torque, are adjustable, sound an alarm noise in overload, and reset automatically when the jam is removed. Design speed range is 1800 rpm or less. 

Specials
Other than standard sprockets and pulleys are an easy and usually inexpensive modification. These clutches are designed as overload protectors only and are not to be run disengaged continuously.
