DTX-LG Miniature Linear Guide

SMN Series
Miniature linear Guides

DTX-LG miniature linear guide combines the compactness of a miniature guide with the high rigidity of a single-rail design, making it an ideal solution for applications with limited space, light loads, and high precision requirements. Compared to standard narrow rails, the wide rail offers greater stability and load capacity in single-rail configurations. It is especially suitable for precision equipment where space is constrained but high accuracy and rigidity are essential, such as semiconductor manufacturing equipment, PCB assembly machines, medical devices, robotic arms, precision measuring instruments, office automation equipment, and other compact linear motion systems. This linear guide is fully interchangeable withthk miniature linear guide THK SSR, linear guideway HIWIN MGN series and iko miniature linear guide IKO LWL, offering similar precision and performance at a more competitive cost.
