High positioning accuracy. The friction coefficient affected by speed is extremely small, allowing for high-precision linear motion with minimal feed;

Maintain long-term stable accuracy. Ideal rolling motion, minimizing rolling friction coefficient, reducing wear of friction contact surfaces, and maintaining walking accuracy for a long time;

Improve the production capacity of the device. The friction is very small, and it carries a relative allowable load and rigidity, so it can be equipped with miniaturization, cost reduction, and energy saving effects;

Simple maintenance. Due to minimal wear and tear, repeated adjustments that do not require precision are necessary. In addition, a small amount of regular oil supply can simplify the lubrication structure;
