A pneumatic cylinder arrangement for lathes and other rotating machines, characterized in that, being static, its support is hollow and of relatively large diameter to allow the passage of the bar to be fastened and of the strut that with its longitudinal movement maneuvers the claws of the plate, being fixed by threaded on the end of said stringer opposite the plate, a piece having the form of a sleeve of greater internal diameter than the external one of the tie to which it is attached, rotates with this supported, internally, on the support of the cylinder intermediate a needle bearing and externally, on another needle bearing located in a corresponding housing provided in a non-rotating hollow part that wraps it, which, in addition to bearing also mounted a ball bearing properly to counteract axial forces, is joined to a piston that moves inside an appropriately closed cavity in pump body functions, pr Actuated in front of the fixed body of the cylinder, which piston moves in one direction or in another forced by the action of air under pressure that enters said cavity by one and the other of two conduits that open respectively on the opposite sides of the piston, which ducts, reversibly by the simple maneuvering of a key, are inlet or outlet of air, there being also provided in the rear part of the hollow that is determined in said part integral to the piston, a ball bearing also appropriately to counteract efforts Axial (Machine-translation by Google Translate, not legally binding)
