SERVO CYLINDER

摘要

The present invention relates to a servo cylinder which is configured to change a rotary motion of a motor into a linear motion of a piston rod using a TM screw or a ball screw; which constructs a linear bushing to allow infinite linear motions of the piston rod inside a housing; which uses high rigidity bearing steel for the housing and the rod; which installs a ball retainer for guiding a row of balls capable of infinite linear motions inside the housing; which has high durability by applying a rotation prevention guide for controlling torsional angles; and which has the linear bushing capable of driving at high speed and maintaining a predetermined precision.
