01. High-Strength Materials
DTX-LG linear guideways 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 square rail 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 guide roller type block SRH corrosion resistant carriage is manufactured in-house with CNC drilling and grinding to ensure accuracy and consistency.
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-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.
06. Boost Your Sales: Distribute roller linear guide ways
For distributors and machine builders seeking heavy load linear guides and heavy-duty square linear carriage solutions, the DTX-LG SRH series delivers long service life and high reliability. It is the ideal linear carriage block and linear guide for CNC applications requiring maximum rigidity and stability.
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.
DTX-LG SRH Roller-Type Square Linear Carriage is fully interchangeable with Hiwin RG square blocks, as well as major brands such as THK, TBI, and IKO. The carriage uses rollers with a double-arc Gothic groove design and forms four-point contact with the SRR linear rail.
As a result, the roller linear guide can withstand much higher loads and provides significantly improved rigidity. This allows it to effectively suppress machine deformation and vibration during machining, ensuring stable precision and excellent processing quality. That’s why SRH blocks are frequently used in CNC grinding machines and large gantry machining centers.
When operating in harsh environments, DTX-LG—as a professional CNC roller bearing linear guide rails manufacturer—can apply advanced surface treatments such as black chrome plating or white chrome electroplating. Our products have passed 72-hour salt spray tests, significantly improving rust and corrosion resistance.
Questions? You’re covered
As a manufacturer of linear motion block, DTX-LG offers professional service from R&D and production to final adjustment. We look forward to exploring new challenges with you.
01. Are DTX-LG SRH blocks interchangeable with other brands?
Yes. DTX-LG SRH is a direct RGH20 / RGH25 / RGH30 / RGH35 replacement block, fully compatible with Hiwin RG series and other leading brands such as THK, TBI, and IKO. This allows distributors to provide customers with drop-in replacement solutions without redesigning the machine.
02. What are the main benefits of SRH roller linear carriage compared to ball-type blocks?
SRH uses a roller linear guide ways design with line contact, providing higher rigidity, better vibration suppression, and much longer service life. This is ideal for customers with heavy-duty CNC machines and precision applications.
03. What type of applications can I target as a distributor?
These heavy load linear guides are commonly used in CNC grinding machines, large gantry milling machines, five-axis machining centers, and other equipment requiring superior rigidity and precision.
04. Why should a customer upgrade to SRH from ball-type carriages?
Customers will benefit from improved machining accuracy, reduced deformation under heavy cutting, and extended service life. These are strong selling points that you, as a linear roller guide bearings distributor, can use to demonstrate ROI to end users.
05. What sizes of SRH blocks are available?
We offer a complete range including RGH15 / RGH25 / RGH30 / RGH35/ RGH45/ RGH55/ RGH65/ RGH85 / RGH100 replacement hiwin block options. Distributors can stock the most common sizes to meet urgent customer needs.
06. Do you provide technical support and marketing materials?
Yes. DTX-LG supply installation manuals, load ratings, CAD drawings, and product brochures to help distributors present the SRH series as a premium roller linear guide ways solution.
07. How fast can you deliver?
With 24/7 production and automated precision machining, we can ship standard linear guideways quickly and custom-length rails or treated blocks within short lead times.
