TITLE Friction Interface Unit For A Clutch And A Brake ABSTRACT OF THE DISCLOSURE A friction interface unit is shown according to the teachings of the present invention for use with a clutch, a brake, or a clutch-brake. The unit includes a hub having an annular friction flange and adapted to receive a shaft. A first housing portion is rotatably supported by a pair of bearings interposed between and in radial alignment with the hub and the first housing portion. The first housing portion is adapted to be associated with a sheave, an anchor mount for a brake, or a ring disc for a caliper brake. A second housing portion is further provided which has a cen- tral circular portion and which is bolted to the first housing portion thereby forming a full housing. Also included is a piston having an annular flange extended over said central circular portion to form a cylinder with a single O-ring. The second housing portion has a rotary air union mounted thereon for introducing fluid pressure into the cylinder to activate the piston to cause a friction facing mounted thereon to engage the friction flange for rotation of the hub. In operation, i.e., engagement, the entire unit rotates and when rotating there is no relative motion between the races of the bearings thus measurably increasing bearing life.
