Application industry
Crossed roller guide is a high precision, high load, high rigidity linear motion track, usually used in robots, automation equipment, machining centers, precision measurement equipment and other equipment and systems that need to achieve high precision linear motion.
Cross Roller Guide
Product structure
In the VR type, the roller cage in which the precision rollers are orthogonally combined with each other is used in combination with the V-groove raceway provided on the dedicated track.By assembling two rows of roller guide rails in parallel, the rail system can withstand loads in four directions. In addition, since a preload can be applied to the cross-roller guide, a carriage mechanism with no clearance, high rigidity, and smooth movement can be obtained. Cross-roller guides are widely used in office equipment and peripheral equipment, various measuring instruments, precision equipment such as printed circuit board drilling machines, and slide parts of optical testers, optical tables, manipulation mechanisms, and X-ray devices.
Product features
●Long service life and high rigidity
Using the unique roller holding method, the effective contact length of the rollers has been increased by 1.7 times compared with the previous product, and the pitch interval of the rollers has been shortened, the number of rollers has been increased, and the rigidity has been increased by 2 times, which can obtain 6 times. lifespan. Therefore, it is possible to adequately design safety considerations for vibration and shock problems that are likely to occur in linear motion parts.
●Smooth movement
In the VR type, the roller cages are separated. Since the roller pockets in the cage are in contact with the roller surfaces, there is good lubricating oil retention, so there is no wear and friction, and smooth rolling motion can be obtained
Product accuracy
The accuracy of the rail dedicated to the Cross Roller Guide is divided into high grade (H) and precision grade (P) as shown in the table below
