Product Description

Product Description

A linear guide is a precision motion system that ensures smooth, low-friction movement in a straight line. It consists of rails and carriages with recirculating ball or roller bearings, offering high rigidity, accuracy, and load capacity. Widely used in CNC machines, automation, and robotics, linear guides enhance performance, reduce wear, and enable repeatable linear motion in industrial applications.

Key Features & Advantages

1,High Precision & Repeatability - Engineered for micron-level accuracy, ensuring consistent performance in automated processes.
2,Low Friction & High Efficiency - Recirculating ball/roller bearings reduce resistance, enabling smooth motion with minimal energy loss.
3,Heavy Load Capacity - Robust construction supports radial, moment, and axial loads, making it suitable for demanding industrial environments.
4,Long Service Life - Hardened steel rails and precision-ground surfaces resist wear, extending operational lifespan.
5,Modular & Compact Design - Easy integration into machinery, saving space while maintaining performance.
