The precision circular guide rail belongs to the roller type guide rail and is the foundation and core component of the circular guide rail cyclic motion system. General loop assembly lines, such as belt type assembly lines and drum type assembly lines, have large motion gaps and do not have sufficient rigidity and positioning accuracy. The circular motion system composed of circular guide rails has outstanding characteristics such as high rigidity, efficiency, high positioning accuracy, good anti pollution ability, and higher operating speed, which can well meet the precision automation needs of modern factories.

1. Suitable for use in harsh environments such as dust: The rolling element of the bearing in the roller does not directly contact the guide rail surface, and the bearing has good sealing performance; The ladder type roller scrapes away impurities such as dust and chips from the surface of the ladder type guide rail through "scraping" movement, keeping the surface of the ladder type guide rail clean, making it very suitable for use in harsh environments. If the ball guide operates in an environment with impurities such as dust and chips, its service life will be greatly shortened.

2. Reduced the precision requirements for installation benchmarks: a ladder roller is equivalent to a slider of a ball guide, and the contact between the ladder roller and the surface of the ladder guide is similar to single point contact; This greatly reduces the accuracy requirements for the installation reference surface, and assembly is time-saving and labor-saving.

3. Faster linear speed and higher acceleration: The ladder roller can achieve relatively high linear speed and acceleration when rolling on the roller ladder guide rail surface.

4. Lower noise: The V-shaped groove of the roller bearing and the stepped surface of the roller ladder guide rail have good contour consistency; The smooth rolling of the ladder roller on the surface of the roller ladder guide rail can greatly reduce the noise during high-speed operation compared to the ball guide rail.

5. Lower maintenance and replacement costs: The ladder type guide roller guide rail system can replace worn guide rails or rollers separately without the need for complete replacement; By adjusting the eccentric roller, it is convenient to adjust and obtain the required preload force.

6. Pre tension adjustable at any time: When assembling the roller guide rail, the concentric roller and eccentric roller are used together, and the pre tension force between the roller and the guide rail can be adjusted at any time to ensure smooth operation.

7. Longer service life: In a good working environment, coupled with the easy replacement of rollers, roller guide rails have a long service life.
