01. High-Strength Materials
DTX-LG linear guide components are 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 precision flanged linear 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 linear carriage system 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 flanged linear block for CNC machine.
04. Ensuring Cleanliness and Reliability Before Assembly
Each linear guide rail 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 mini linear guide 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.
DTX-LG’s miniature linear guide systems (mini linear guide) are designed for applications requiring high precision, smooth motion, and compact installation space. Our guides feature a linear recirculating ball carriage with a built-in steel ball retainer, ensuring smooth motion, reduced noise, and easy maintenance. Within the allowed tolerance range, our miniature linear guides are fully interchangeable with most brands on the market, including the Hiwin MGN series and IKO miniature linear guide.
We offer models in sizes MGN5 / MGN7 / MGN9 / MGN12 / MGN15, matching the specifications of most existing miniature linear guides. The highest precision level can reach P-class, meeting demanding requirements for precision linear guideway applications.
DTX-LG also provides stainless steel miniature linear guide bearings for enhanced corrosion resistance. However, stainless steel does not guarantee absolute rust-proof performance under all conditions – proper maintenance and regular lubrication are still required.
DTX-LG H-type low profile mini rail linear guide features an extended block design that supports greater weight capacity compared to the C-type. This allows users to reduce the number of blocks on a single rail, effectively lowering system cost and improving profit margins.
As a dedicated miniature type linear guide manufacturer, DTX-LG provides customized miniature CNC linear guide solutions, including special rail lengths, custom drilling, and other machining services. These guides are widely used in 3D printers, medical devices, automation equipment, and other compact machinery that demand smooth and precise motion.
Choose DTX-LG for reliable, cost-effective, and customizable miniature linear guide systems that integrate seamlessly with your designs – whether you need a linear guideway MGN9 replacement, a precision miniature linear guide bearing, or a fully customized mini rail linear guide solution.

MGN15 linear rail and MGN 15 C Hiwin blocks
Our dimensions match Hiwin MGN square blocks and other common models, making installation easy for existing designs.
04. What preload options do you offer for the linear motion carriage?
We offer three preload classes for our miniature linear motion carriages:
Normal clearance – standard option for smooth motion
No preload – lowest friction, ideal for light-duty applications
Light preload – higher rigidity and precision, suitable for CNC, 3D printing, or measuring equipment
05. What dust-proof configurations are available?
DTX-LG miniature linear guides are designed with effective sealing options:
Standard: Each block comes with end seals (oil scrapers) to prevent dust and debris from entering the ball tracks.
Enhanced: For smn9 (MGN9 linear rail) and smn12 (MGN12 miniature linear rail slide), we offer optional bottom seals for added dust protection.
