SBR30 Linear Shaft Overview
The SBR30 supported linear shaft is a high-rigidity linear motion component designed for precision sliding systems. It consists of a 30mm hardened steel shaft mounted on an aluminum support base, which significantly reduces shaft deflection compared to unsupported round shafts.
The supported structure allows the linear shaft to maintain excellent stability even over long travel distances, making it widely used in CNC machines, automation equipment, and industrial motion systems.
DLY manufactures high-quality SBR series linear shafts with strict quality control and reliable performance for global industrial applications.

Key Features of SBR30 Linear Shaft
High Rigidity Structure
The aluminum support base prevents shaft bending and improves load capacity.
Smooth Linear Motion
Compatible with SBR30UU bearing blocks for smooth and stable movement.
High Hardness Steel Shaft
The shaft is made of high-carbon steel with surface hardening treatment to ensure durability and wear resistance.
Easy Installation
Pre-machined mounting holes on the base allow quick installation onto machine frames.
Cost-Effective Linear Motion Solution
Compared with profile linear guides, SBR supported rails provide an economical solution for many automation systems.
