These clutch brakes fit in tight quarters

Posidyne clutch brakes (photo) can be ordered with special pads cast into the main housings to mount an adjustable motor base, allowing the motor to sit atop the clutch brake in a space-saving “piggyback” design. This arrangement also includes a gear belt drive from the motor to the input shaft and an enclosed belt drive guard. The Posidyne features oil shear technology that allows rapid and precise stopping, starting, speed change and positioning, all without adjustment or maintenance. Posidyne piggyback clutch brakes are well suited for applications with frequent start/stop cycles, and high cycle rates (up to 300 cycles per minute). Posidyne clutch/brakes feature a multiple disc design that produces high torque from a small package. Recirculating the fluid dissipates the heat of engagement, which is a common cause of downtime with other clutch/brake assemblies. Multiple sizes are available to suit applications from 0.5 to 350 hp. — Force Control Industries, Inc., Fairfield, Ohio
