Screw drives Bosch Rexroth
Linear technology Bosch Rexroth
Screw drives from Bosch Rexroth convert rotation into precise linear motion. The programme covers ball screw assemblies with flanged and cylindrical nuts of the FEM, FED, SEM and ZEM series (for example FEM-E-S 50X10, FED-E-B 32X32, SEM-E-S 40X10, ZEM-E-K 12X5) with screw diameters from 12 to 50 mm and leads from 5 to 10 mm. It is completed by fixed bearings (LAF-C-A 20), lock nuts (NMZ 30X1,5) and thread rings (GWR 30X1,5).
Typical applications: Screw drives power feed axes in machine tools, handling and positioning where accuracy and rigidity matter. Selection follows screw diameter, lead, required load rating and nut type (flanged or cylindrical) plus the matching bearing. Fixed bearings, lock nuts and thread rings complete the screw unit.
