Roller Linear Guides Block SRW

SRW15/20/25/30/35/45/55/65

The DTX-LG SGR guide rail adopts the DF (45°-45°) design with circular arc grooves. During installation, due to the elastic deformation of the steel balls and the transfer of the contact points, even if there is some deviation on the installation surface, it can be absorbed by the inside of the linear guide slider, producing the effect of automatic self-alignment and obtaining high-precision, stable and smooth motion. DIX-LG has standard length rails in stock to meet customer needs. If you order non-standard length rails, the end face distance B should not be larger than 1/2P to prevent the instability of the rear end of the rail assembly due to excessive B, which will reduce the accuracy of the linear guide.

DTX-LG heavyload linear slide rails feature

DTX-LG SGR Linear guide rail component

DTX-LG linear guides rail feature higher C/Si/Cr content than leading Taiwanese and Japanese brands, improving rigidity while maintaining full interchangeability.

Questions? You’re covered

Yes, DTX-LG SRW blocks are 100% interchangeable with Hiwin RGW flange-type blocks in models like RGW20, RGW25, RGW30, and RGW35.

01. Can the SRW flange block replace Hiwin RGW blocks?

The SGH series from DTX-LG is a high-precision linear guide system, designed for smooth linear motion and compatible with Hiwin’s HGH series.

We offer SRW flange blocks in sizes SRW20, SRW25, SRW30, and SRW35-65, corresponding to Hiwin RGW20~65 standards.

Absolutely. SRW blocks are engineered for high stiffness and stability, making them ideal for CNC machines, milling equipment, and automated systems.

Yes, SRW blocks are designed to slide directly onto Hiwin RG linear rails without the need for modification or adapters.

Yes. We provide various preload options (Z0, Z1, Z2) and precision grades (Normal, High, Precision) to meet your technical needs.
