Product Features

Feature 1: Has high-precision dimensional tolerances and is widely used in various precision equipment.
Feature 2: Uses bearing steel (S45C or GCr15) with excellent wear resistance and SUS440C or high-hardness corrosion-resistant steel, which are high-frequency quenched to enhance wear resistance while maintaining original toughness.
Feature 3: Various additional processing options are available to meet different usage environments.
Feature 4: Usually used in combination with linear bushing products, it provides excellent linear guidance. Compared to general shaft and bushing structures, even during high-speed reciprocating motion, there is minimal wear.

Example of Use

Standard Linear Motion Mechanism	Functions of Standard Linear Motion Mechanisms (1) Using two guide shafts in parallel effectively prevents workpiece rotation (2) Improves the accuracy and load capacity of linear motion. (3) High-speed reciprocating motion can be achieved through the combination of guide shafts and linear bushings. (4) Lower running resistance, resulting in less wear on the corresponding workpiece.
