Features of  RA Series

Cross roller bearing, because the divided inner ring or outer ring, after the rollers and spacers are installed, it is fixed with the cross roller ring to prevent separation from each other, so operate when installing the cross roller ring simple. Since the rollers are arranged in a cross, only one set of cross roller rings can bear loads in all directions. Compared with the conventional model, the rigidity is increased by 3 to 4 times. At the same time, because the inner ring or outer ring of the cross roller bearing has a two-part structure, the bearing gap can be adjusted, and even if preload is applied, high-precision rotational movement can be obtained.

Applications

Suitable for joints or rotating parts of industrial robots, rotating tables of machining centers, rotating parts of manipulators, etc.
