Description
The ST20 20mm Linear Motion Shaft with Support by KHS-LG is a precision-ground linear shaft system designed to provide stable and accurate linear movement in CNC and industrial automation applications. Manufactured from C45 steel, the shaft offers high strength, rigidity, and durability suitable for demanding mechanical operations.
The supported configuration includes an aluminum base support rail that enhances structural stability and minimizes shaft deflection under load. This design improves performance in longer travel applications where unsupported shafts may experience bending. The precision ground surface ensures smooth interaction with linear bearings, providing consistent motion and reduced friction.
This supported linear shaft system is widely used in CNC machinery, sliding assemblies, and industrial automation setups where precision alignment and reliable motion control are critical.
