The QH series of silent ball linear guides with chain belts still adopt the four-row single circular arc groove contact design. To further enhance the product's competitive edge, each row of steel balls is equipped with a silent chain belt. This prevents the mutual friction between steel balls and effectively reduces the noise during the operation of the guide pair. It also enables the steel balls to enter and exit the load and non-load zones more smoothly, significantly improving the stability and smoothness of operation. It is particularly suitable for high-speed, quiet and low-dust emission high-tech industries.

QH Series- Quiet Linear Guideway
Features of the QH Series
1. Low Noise Design
With SynchMotion technology, rolling elements are interposed between the partitions of SynchMotion to provide impoved circulation. Due to the elimination of contact between the rolling elements, collision noise and sound levels are drastically reduced.
2. Self-Lubricant Design
The partition is a grouping of hollow ring-like structures formed with a through hole to facilitate circulation of the lubricant. Because of the special lubrication path design, the lubricant of the partition storage space can be refilled. Therefore, the frequency of lubricant refilling can be decreased.
The QH-series linear guideway is pre-lubricated. Performance testing at a 0.2C (basic dynamic load) shows that after running 4,000km no damage was apparent to either the rolling elements or the raceway.
3. Smooth Movement
In standard linear guideways, roling elements on the load side of the guide block begin rolling and push their way through the raceway, When they contact other rolling elements they create counter-rotational friction. This results in a great variation of rolling resistance. The QH linear guideway, with SynchMotion technology prevents this condition. As the block starts to move, the rolling elements begin rolling consecutively and remain separated to prevent contact with one another thus keeping the element's kinetic energy extremely stable in order to effectively reduce fluctuations in rolling resistance.
4. High Speed Performance
The SHAC-QH series offers excellent high-speed performance due to the partitions of the SynchMotion structure. They are employed to separate the adjacent balls thereby resulting in low rolling traction and the metallic friction between adjacent balls is eliminated.
