High Precision Self Aligning Linear Guide Carriages HIWIN Compatible GHH
SEXGL linear guides redefine reliability in high-demand automation systems, trusted by industry leaders like BYD (electric vehicle assembly lines) and BOE (LCD panel handling robots) across North America, Europe, Southeast Asia, and South America.This series of linear guides and carriages is specifically engineered as a direct replacement for HIWIN's HG/EG/QH mainstream series. Incorporating cutting-edge international technologies and domestic innovative processes, it delivers high-performance, reliable linear motion solutions for CNC machine tools, automation equipment, semiconductor manufacturing, and other advanced applications. Through structural optimization, material upgrading, and intelligent integration, the product matches core performance metrics of top-tier international brands—including precision, load capacity, and service life—while leveraging cost-effectiveness, rapid delivery, and customized services to help customers reduce costs and enhance operational efficiency.
Core Technical Advantages
1. Precision Positioning
Achieves positioning accuracy of ±0.008mm (standard grade) to ±0.002mm (ultra-precision grade), with repeatability of ±0.005mm, meeting the demanding requirements of high-precision machining and metrology applications.
2. Self-Aligning Design
Features a four-row arc groove structure (45° contact angle) that automatically compensates for installation errors, eliminating motion fluctuations caused by equipment deformation or assembly deviations. This ensures stable operation even in complex working conditions.
3. Low-Friction Performance
Integrates a ball recirculation system with precision-ground raceways to achieve a friction coefficient as low as 0.0015, enabling smooth motion and energy-efficient operation.
