SERVO CYLINDER

摘要

The present invention relates to a servo cylinder which converts a rotational motion of a motor into a linear motion of a piston rod by using a TM screw or a ball screw and combines a linear busing to the piston rod inside a housing so as to enable an infinite linear motion, wherein the housing and the rod are made from high-rigidity bearing steel. In addition, a ball retainer is provided for guiding a row of balls capable of infinite linear motion inside the housing, an anti-rotation guide is applied for controlling the angle of torsion to enable obtainment of high durability, high-speed travel is enabled, and the linear busing is capable of maintaining a predetermined precision.
