Bosch Rexroth linear motion
Screw drives
Bosch Rexroth screw drive components include axial bearing units, springs and further accessories for ball screw and lead screw drives. The range covers axial bearing groups in the LGF, LGL and LGN series across a wide range of dimensions, as well as spring elements for screw spindle preloading. These components provide the structural support of the screw spindle at the fixed and floating bearing end, and are decisive for the axial stiffness and positioning accuracy of linear drives.
