01. High-Strength Materials
DTX-LG linear guide rail and carriage 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 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 rail and blocks 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 flanged linear block for CNC machine.
04. Ensuring Cleanliness and Reliability Before Assembly
Each heavy load linear guide 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 linear motion components 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 SG series linear guide assembly are fully interchangeable with the Hiwin HG series linear guideway, as well as other major brands such as THK, TBI, and IKO. Three types of carriages are available — flange type, square type, and the L-type carriage, which has the same assembly height as the flange type, greatly reducing space constraints. The DTX-LG assembly offers travel accuracy up to 2 microns, making it ideal for heavy load linear guide applications and other heavy duty linear track system requirements.
To simplify ordering, you can simply send us the brand and model you wish to replace, and our engineers will recommend the corresponding DTX-LG model. Alternatively, you may send us your required assembly line guide drawings directly for quick matching.
As one of the leading linear guideways manufacturers, DTX-LG not only provides customized lengths, mounting hole patterns, anti-corrosion treatments, and engineering support for end-users, but also comprehensive services for linear guide distributor partners. These include customized packaging, dedicated training, joint marketing campaigns, lead conversion support, and consignment stock programs — where we store a certain quantity of standard heavy duty linear rail products in the distributor’s warehouse, allowing settlement after sales to reduce financial pressure.
