Bosch Rexroth R151231013 Ball Nut FEM-E-S 32X5RX3

Bosch Rexroth R151231013 Ball Nut FEM-E-S is a flange‑mounted, single-ball-nut in the FEM-E-S family, sized for a 32 mm bore with a 5 mm lead (32x5). The “32x5” designation identifies the nut’s nominal diameter and lead, making it a compact, high‑precision component for Rexroth ball‑screw assemblies. As part of Rexroth’s ball‑screw lineup, the FEM-E-S nut provides recirculating‑ball guidance that translates rotary motion from the screw shaft into precise linear displacement, enabling repeatable positioning in automation equipment and machine tooling. The R151231013 designation corresponds to a specific flange‑nut configuration within this series, designed to pair with compatible Rexroth screws to form a robust linear‑motion drive. In practical use, this nut supports smooth, accurate travel and reliable performance under continuous operation in industrial settings where tight tolerances and steady motion are essential.
