DTX-LG Heavy Duty Linear Slide Rails SRR
SRR 15/20/25/30/35/45/55/65
Fully Interchangeable THK SRG / HIWIN RG
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.

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.
