High Rigidity Dual Axis Linear Guide Rails Designed for CNC
SEXGL specializes in manufacturing high-performance linear guides that redefine reliability in industrial automation. Trusted by global partners like BYD (electric vehicle production) and BOE (display manufacturing), our linear motion systems power operations across North America, Europe, Southeast Asia, South America, and South Korea.
The Dual-Axis Linear Guide Rail SBR/SGB series combines precision engineering with modular design to deliver high-performance linear motion solutions for industrial automation, CNC machinery, and precision equipment. This product line integrates advanced rolling-element technology with robust materials, ensuring smooth operation, high rigidity, and long-term reliability in demanding applications.
Product Features
-
Dual-Axis Design for Enhanced Stability
The SBR/SGB series features a dual-axis configuration with parallel guide rails and carriages, providing superior load distribution and resistance to lateral forces.
-
High Rigidity & Low Friction
Constructed with precision-ground steel rails and recirculating ball/roller bearings, the SBR/SGB series achieves high rigidity (up to 20 kN) and low friction coefficients (μ ≤ 0.002), minimizing energy consumption and wear. The SBR variant uses roller bearings for heavy-duty applications, while the SGB employs dual-axis roller wheels for high-speed, low-noise operation.
-
Self-Aligning Capability
The SGB model incorporates adjustable eccentric wheels, allowing users to eliminate clearance and achieve zero backlash through simple preload adjustments.
-
Interchangeability & Easy Maintenance
The modular design enables quick replacement of individual components (rails, carriages, or bearings) without disassembling the entire system.
-
Corrosion Resistance
Both SBR and SGB variants are available with anodized aluminum alloy or stainless steel components, offering excellent corrosion resistance for use in harsh environments such as medical equipment, food processing, and semiconductor manufacturing.
