SGR 15/20/25/30/35/45/55/65
Fully Interchangeable HIWIN HGR
The SRR series from DTX-LG features standalone linear guide rails for roller-type blocks, manufactured using three-sided precision grinding technology to ensure outstanding straightness, parallelism, and surface quality. Sizes are available from SRR15 to SRR65, and all rails support H / P / SP / UP precision classes, making them suitable for both standard and ultra-precision linear motion applications. Designed for compatibility with square or flange-type roller blocks, SRR rails deliver stable motion accuracy, long service life, and seamless interchangeability with global brands such as THK and HIWIN.

- Significant Cost Advantage
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.
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.
