Structure of crossed cylindrical roller bearing:
Cross roller bearing is a special type of bearing with split Inner Ring and rotating outer ring. Because the split inner or Outer Ring is fixed to the cross roller shaft ring after the roller and spacer holder are installed, to prevent separation, the installation of the cross roller shaft ring is simple. Because the rollers are arranged crosswise, only one set of crosswise roller shaft ring can bear the load in all directions, and the rigidity is 3 ~ 4 times higher than the traditional model. At the same time, because the inner ring or outer ring of the crossed roller bearing is two-divided structure, the bearing clearance can be adjusted, even if it is preloaded, it can also achieve high-precision rotary motion. Moreover, because of its special structure, it is usually used as a joint bearing in industrial robots.
