Low Profile Linear Guides Block SEH

SEH 15/20/25/30/35

Hiwin EGH interchangeable linear block

DTX-LG’s low profile linear guide block are designed as an affordable EGH block alternative, fully interchangeable with HIWIN’s EG series (such as HIWIN EGH 20 and HIWIN EGH 20 CA, hiwin egh 25, hiwin egh 25 ca, but at nearly half the cost for the customer. Compared with the SGH heavy-duty square blocks, the lower height keeps the equipment’s center of gravity closer to the rail, improving overall stability and making them ideal for high-speed motion or applications where inertia must be minimized. Typical uses include transport systems, electronic and semiconductor equipment, and precision inspection devices. As a linear motion components manufacturer, DTX-LG provides precision grades C, H, and P across models 15, 20, 25, 30, and 35, corresponding to EGH 15, EGH 20, and so on. The end caps are specially designed with a side-lubrication port for installing straight grease nipples, enabling convenient side lubrication. These blocks are a perfect match for low profile linear guide rail systems and deliver a reliable, cost-effective linear guideway carriage solution for a wide range of automation needs

Why DTX-LG linear guideway manufacturers?

01. High-Strength Materials

DTX-LG precision linear guide is manufactured from premium steel and undergoes advanced heat treatment, achieving a surface hardness of 59–62 HRC. This ensures excellent wear resistance, higher load capacity, and extended service life even under heavy-duty conditions.

Each compact linear guide block is equipped with high-quality steel balls hardened to 61–66 HRC. The superior hardness provides outstanding rolling performance, enhances load distribution, and guarantees smooth, precise linear motion with minimal friction.

02. Design in Taiwan, made in china

Each SGW corrosion resistant carriage is manufactured in-house with CNC drilling and grinding to ensure accuracy and consistency. With 16 production lines and an annual output of 3,600,000 pieces, DTX-LG guarantees strict quality control, large-scale supply, and reliable delivery worldwide.

03. Advanced Self-Lubrication System

A built-in lubrication mechanism is integrated into the end cap, consisting of an oil storage unit and an oil release unit. The oil guide element inside not only absorbs and stores oil but also gradually releases it to the raceway through its special structure. This design ensures continuous lubrication, significantly reduces maintenance requirements, and keeps the block running reliably over long periods. Idea Hiwin EGH replacement

04. Ensuring Cleanliness and Reliability Before Assembly

Each heavy-duty linear guide block undergoes a thorough ultrasonic cleaning process to remove machining residues, fine metal particles, and surface impurities. This is followed by hot air drying to eliminate moisture and prevent corrosion. Only after these cleaning and drying steps are completed does the block proceed to the assembly stage, ensuring that every SGH block maintains a clean, contaminant-free surface for smooth motion and long-term reliability.

05. A Full-Cycle ISO Quality Management System

DTX-LG has obtained multiple ISO certifications and fully implements standardized ISO quality assurance management processes across every stage of production. From raw material inspection and machining to assembly and final testing, each step strictly follows ISO guidelines. This ensures product consistency, traceability, and compliance with international quality standards, reinforcing our commitment to delivering reliable and globally recognized linear guide rail & carriage assemblies.
