Bosch Rexroth Planetary Screw Assembly

Bosch Rexroth Planetary Screw Assembly

Often called roller screws, the Planetary Screw Assembly PLSA is a cost-effective, high-performance screw drive system that uses precision-ground threaded rollers (planets) that rotate around the screw, converting rotary motion into linear motion. Their compact design makes them easy to integrate into applications requiring high load capability, precision, and low environmental impact. Rexroth’s economical, high quality PLSAs ship quickly, and offer an efficient drive solution for applications requiring up to 25,000 pounds of pressure.
