01. CNC Precision Drilling Machine for linear guide rails
DTX-LG Adopting a Mirror-Symmetric Drilling System, the dual-spindle real-time synchronization error ≤0.003mm ensures balanced thermal dissipation across the guideway cross-section.
This eliminates arc-shaped deformation caused by unilateral processing, guaranteeing full-length straightness stability ≤0.005mm/m (exceeding ISO Class C precision standards).
02. Smart Batch Sampling: Precision Assured, Costs Controlled
Every DTX-LG lot undergoes rigorous sampling, ensuring ±0.005mm/m straightness & ISO Class C+ precision. Zero-defect guarantee.
03. Bulk Production Excellence for Distributor Inventory Assurance
Mass-produced with 100% batch sampling, ensuring 24hr-ready stocks for distributors. Guaranteed ±0.005mm precision at volume pricing.
04. High-rigidity material
DTX-LG linear guides rail feature higher C/Si/Cr content than leading Taiwanese and Japanese brands, improving rigidity while maintaining full interchangeability.
DTX-LG SRR Roller-Type Linear Guide is fully interchangeable with the Hiwin RG series. The rolling element it accommodates is a cylinder (line contact). The rollers contact the rail groove along a line, which greatly increases the contact area and distributes the load over a wider surface. This allows the guide to withstand significantly higher loads with greatly improved rigidity—an essential feature for heavy cutting, large loads, and applications with strong vibration or impact.
This roller linear guide effectively suppresses machine deformation and vibration during machining, ensuring high processing quality. Under the same load conditions, the contact stress is lower, giving the roller guide a much longer service life compared to a ball guide.
In high-end gantry machining centers, this type of linear guide rail and carriage is often used on the Z-axis. It is widely applied in:
- Gantry milling machines
- Floor-type boring machines
- Large grinding machines
- Five-axis machining centers
- Punch presses, stamping presses, and press brakes
Questions? You’re covered
As a manufacturer of linear guide rails, DTX-LG offers professional service from R&D and production to final adjustment. We look forward to exploring new challenges with you.
01. What makes DTX-LG SRR different from other linear guide rails?
DTX-LG SRR is a roller linear guide with line contact instead of point contact, offering much higher rigidity and load capacity. As a linear guide rail and carriage factory, we ensure precise manufacturing and full interchangeability with Hiwin RG series rails and blocks, making it easy for distributors to sell as a direct replacement.
02.Are DTX-LG SRR linear guides interchangeable with other brands?
Yes. These cnc linear guide rails are designed to be 100% interchangeable with Hiwin RG series, including popular sizes like CNC linear guide HGR30, allowing distributors to help customers replace or upgrade without machine redesign.
03. What industries use this type of roller linear guide ways?
DTX-LG roller linear guide ways are widely used in heavy-duty CNC equipment such as gantry milling machines, floor-type boring machines, large grinding machines, five-axis machining centers, punch presses, stamping presses, and press brakes.
04. Why should I offer SRR instead of ball-type linear guides?
Compared with ball guides, these cnc roller bearing linear guide rails have higher load capacity, lower elastic deformation, and much longer service life. For customers seeking linear guide for CNC applications with heavy loads, vibration, or shock, this is a superior solution.
05.What is the main selling point for my customers?
The SRR series provides exceptional stability, accuracy, and longevity. You can market it as a heavy duty linear slide rails solution that reduces downtime, maintains precision, and improves surface finish quality for end users.
06. Do you provide marketing materials for distributors?
Yes. As a professional linear guide rail and carriage factory, we supply brochures, CAD drawings, load charts, and installation manuals to help distributors sell linear motion guides more effectively.
07.Can I order small quantities for stock?
Yes. We support distributors with small-volume orders for common CNC linear guide rails sizes so they can maintain local inventory and provide fast delivery to customers.
08. What sizes and precision grades are available?
DTX-LG SRR series offers a full range of sizes, including SRR15,(hiwin RG15), SRR25 (hiwin RG25), SRR35 (hiwin RG 25),SRR35 (hiwin RG 35), SRR 45(hiwin RG 45),SRR55 (hiwin RG 55) and more. Precision grades ( H, P) are available to match different machine tool requirements and applications.
