Product Description

Product Description

KGG High Quality Cold Rolled Ball Screw - GSR Series

Our GSR Cold Rolled Ball Screw delivers reliable linear motion for cost-sensitive applications in general automation, material handling, and industrial machinery, etc. Our precision cold-rolled screw design provides excellent value, consistent accuracy, and high efficiency. Built for durability, it ensures stable performance in medium-load, moderate-speed, and various industrial environments.

Specification

Advantages

Load Capacity & Service Life
The GSR series utilizes precision cold-rolling technology that enhances the surface integrity and grain structure of the screw shaft, providing excellent dynamic and static load ratings. Through optimized ball groove geometry and precise heat treatment processes, the load is distributed evenly across multiple contact points, resulting in improved impact resistance and extended service life. The hardened raceways and precision-grade balls work in conjunction to deliver reliable performance under continuous operation, making it suitable for various industrial applications requiring consistent load-bearing capacity.

Accuracy & Repeatability
Employing advanced cold-rolling manufacturing techniques, the GSR series achieves consistent lead accuracy and excellent positioning repeatability. The precision-formed ball grooves ensure smooth ball recirculation and minimal vibration during operation. Special attention to thread profile consistency and optimized preload adjustment allows for precise motion control, making it ideal for applications demanding reliable positioning performance and minimal deviation.

Efficiency & Cost-Effectiveness

The cold-rolling manufacturing process enables high production efficiency while maintaining competitive pricing. The optimized design reduces energy consumption through lower friction coefficients and efficient power transmission. This cost-effective solution provides excellent value for general automation applications, offering balanced performance characteristics without compromising reliability or durability.

Application
Widely used in electronic device assembly equipment, liquid filling machines, welding apparatus, circuit board press-fitting systems, LCD panel manufacturing equipment, semiconductor processing machinery, LED production lines, and biomedical devices. The series is particularly suitable for industrial automation applications requiring reliable performance and cost efficiency.
