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.
