Request Information
The Posidyne® is the backbone of the Force Control line of Clutch/Brake products. Constant development of new designs and materials has enabled the Posidyne® to become a work horse on today's modern high production machinery. The basic Posidyne® is a combination of a clutch and brake in a single unit. The multiple stacks enclosed in a cast iron housing ,cooled and lubricated by recirculating fluid are unaffected by outside contaminants and have a tremendous ability to dissipate heat. With their built in mechanical strength this makes the Posidyne® an excellent choice for applications of heavy loads and high cycle rates.

 N/A Thermal HP ratings based on 1800 RPM and 70° ambient temperature. Higher thermal ratings available with forced lubrication. Consult factory with application details.
For Water cooled Units Cooling water flow requirements in GPM equals .10 x thermal horsepower Oil Capacity is only approximate. Always fill unit to center of sight gauge.
Air pressures are at maximum torque . Operating pressures are generally much lower. Refer to Section 15 “Pressure vs. Static Torque” charts on pages 15.7 & 15.8 for proper pressure settings.
Size 11 and 14 Posidyne rated @ 1200 RPM. Fan cooled only. These sizes can run up to 1800 RPM with the External Cooling System shown below. CF- Consult Factory
Top porting and bottom porting are both supplied. The use of bottom porting is recommended to purge contaminants out of the pistons when they are exhausted. The use of top porting will not purge the pistons.
