Rexroth Planetary Roller Screw Drive System

Describe

Through the PLSA planetary roller screw drive system, Bosch Rexroth has further expanded the application field of its screw drive system, which can move high loads quickly. In the planetary roller screw drive system, a plurality of planetary rollers are arranged symmetrically on the circumference of a nut. These planetary rollers rotate around the rolling threaded screw shaft and rotate in a direction parallel to the shaft to produce linear motion. The greater number of contact surfaces inherent in the structure brings high axial rigidity and load-bearing capacity, thus realizing a longer service life. PLSA can obtain the highest positioning accuracy and repeat positioning accuracy even under the smallest stroke.
