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 Advantages1. Precision PositioningAchieves 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 DesignFeatures 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 PerformanceIntegrates 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.
