DTX-LG SGR linear guide rails are fully interchangeable with the Hiwin HG series linear guideway and are available in lengths up to 6 meters. The rail joint gap is less than 0.1mm, ensuring smooth motion with a maximum travel accuracy of 2 microns. Manufactured from S55C bearing steel and heat-treated to a surface hardness of 59–62 HRC, these linear slide rails deliver superior durability and precision. As a linear guide rail and carriage factory, we provide additional protection for harsh production environments — including dust caps and optional stainless steel dustproof belts — to effectively block chips and debris, improving machine safety and reliability. The SGR square block linear guide rail is designed to work perfectly with SGH and SGE blocks, offering a robust linear slide guide rail solution ideal for linear guides for CNC machines and other high-precision applications.
