Load Capacity & Service Life
The GG ground ball screw series features precision-ground raceways that optimize load distribution across multiple ball contact points, significantly enhancing both dynamic and static load ratings. The hardened steel construction (HRC 58+) combined with precision ball matching ensures excellent wear resistance and extended service life. Through advanced manufacturing processes, the GG series achieves superior impact resistance and maintains reliable performance even under continuous heavy-load conditions, providing long-term operational stability.
 
Precision Grades & Accuracy
Available in multiple precision grades including C5, C7, and C10, the GG series meets diverse application requirements for positioning accuracy. The precision grinding technology ensures consistent lead accuracy with minimal cumulative pitch error, while optimized preload adjustment enables precise clearance control. These features guarantee micron-level positioning repeatability and smooth motion characteristics, making the series suitable for applications demanding high-precision performance.

Speed Performance & Rigidity

Engineered for high-speed operation, the GG series incorporates optimized ball circulation systems that minimize vibration and noise at elevated speeds. The ground thread profile provides excellent surface contact with the balls, enhancing rigidity and reducing elastic deformation under load. This ensures stable performance during rapid acceleration and deceleration, maintaining precision in high-speed applications while offering excellent dynamic response characteristics.
 
Application
High-precision CNC machine tools, semiconductor manufacturing equipment, industrial robotics, precision measuring instruments, optical processing equipment, medical devices, automotive manufacturing systems, and various industrial automation applications requiring reliable precision motion control.
