Product Description

Product Description

KGG High Quality Ball Screw with Metric Thread - GLR Series

Our GLR Ball Screw with Metric Thread delivers precise linear motion for general industrial applications in automation, material handling, and positioning systems, etc. Our standardized metric thread design provides reliable performance, good accuracy, and easy integration. Built for durability, it ensures consistent operation in medium-load, standard-speed, and various industrial environments.

Specification

Advantages

Load Capacity & Service Life
The GLR series features a standardized metric thread design that ensures reliable load distribution and consistent performance. Manufactured from high-quality S55C steel with induction hardening treatment, the screw shaft achieves surface hardness of HRC 58 or higher, providing excellent wear resistance. The optimized ball circulation system effectively distributes loads across multiple contact points, while the precision heat treatment process enhances impact resistance and extends service life under continuous operation conditions.
 
Precision Grades & Accuracy
Available in C5, C7, and C10 precision grades, the GLR series offers axial clearances of 0.005mm (C5), 0.02mm (C7), and 0.05mm or less (C10) to meet various application requirements. The metric thread standardization ensures compatibility with international systems, while maintaining precise positioning accuracy and repeatability. This makes the series particularly suitable for applications requiring reliable performance with standard metric specifications.

Speed Performance & Efficiency

The GLR series delivers smooth operation at moderate speeds with good acceleration characteristics. The standardized metric thread design reduces friction and ensures efficient power transmission, while the precision manufacturing process maintains consistent performance. The series demonstrates reliable operation in applications requiring frequent cycling and directional changes, offering balanced performance for general industrial use.
 
Application
Industrial automation equipment, material handling systems, packaging machinery, general positioning devices, assembly equipment, printing machinery, educational equipment, and other applications requiring standardized metric components with reliable performance and cost-effectiveness. The series is widely used in various industrial sectors where metric standardization and consistent performance are essential requirements.
