<p>A double acting power chuck has an air feed to the chuck body with a static feed ring supported on the housing component in a recess. This feed ring is guided axially and sealing elements are inserted in it, in machined recesses. For the axial guidance of the ring (11), the two face sides (23, 24) and for the adjacent side walls (21, 22) of the housing component are support faces (25, 26, 27, 28) with continuous recesses (29, 30, 31, 32). One or more labyrinth covers (33, 34) connect outwards to these in the face sides of the ring and/or the side walls of the housing component. The continuous recesses (29, 30, 31, 32) are formed by radial pockets equally distributed over the circumference.</p> |
