Screw assemblies Rexroth offers a wide range of screw assemblies. Screw assemblies are units converting rotary motions into linear motions or vice versa. In this connection, the most important products are the ball screw assembly and the planetary screw assembly. As user, Rexroth will always provide you with the suitable product for your specific tasks. Ball screw assembly Rexroth ball screw assemblies provide the constructor with manifold possibilities for solving transport and positioning tasks with driven spindle or also driven nut.
