Low Profile Linear Guides Rail SER

SER 15/20/25/30/35

Fully Interchangeable with HIWIN EGR

DTX-LG SER low profile linear rail system is a reliable Hiwin EGR replacement rail, designed to offer an efficient and cost-effective alternative to Hiwin EGR profile rails. Unlike the SGR linear rail, it features a low-profile linear guide rail that provides exceptional stability and high load-bearing capacity. This compact linear motion rail can undergo multiple surface treatments, including black chrome plating, electroplating chrome (white chrome), and blackening. Following treatment, the guides pass a rigorous 72-hour salt spray test, ensuring excellent rust and corrosion resistance, which significantly extends the lifespan of the product.

Additionally, the DTX-LG guide is crafted with precision using a 17-axis fully automated drilling machine, guaranteeing a consistent rail joint gap of less than 0.1mm. This ensures smooth motion and precise alignment, even in high-performance environments.

Why DTX-LG linear guide rail?

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).
