In the cross rail, the roller holders in which the precision rollers are combined with each other are used in combination with the 90° V-shaped groove rolling surface provided on the dedicated rail. By assembling the two rows of roller guides in parallel, the rail system can withstand loads in four directions. Further, since the preload can be applied to the cross roller guide rail, a sliding mechanism having no gap and high rigidity and a light movement can be obtained.
The cross roller guide rail is widely used in precision equipment such as office equipment and its external equipment, various measuring instruments, printed circuit board drilling machines, or slider parts of optical measuring equipment, optical tables, operating mechanisms, X-ray devices, and the like.
