|Type:||Cross Roller Bearing||Internal Diameter:||50|
Cross roller bearing  is a special type of bearing with inner ring and outer ring rotation. Because of the inner and outer ring divided into, roller and interval retainer, and cross roller collar fixed together, separated from each other to prevent the installation of cross roller collar simple operation. Because roller cross arrangement, so only 1 sets of cross roller collar can withstand various direction load, compared with the traditional model, increase the rigidity of 3~4 times. At the same time, because the cross roller bearing inner ring or outer ring is two split structure, the clearance of the bearing can be adjusted, even if the pre load is applied, it can also obtain high precision rotary motion. In addition, because of its special structure, it is commonly used in industrial robots to make joint bearings. The inner ring and the outer ring roller, interval crossed at right angles to each other. They can also suffer from the direction of the load (such as axial thrust, or momentum loading). Because of the roller and the track surface into linear contact, therefore, the bearing load and elastic deformation of the possibility is very small. This type of bearings are widely used in such as industrial robots, automatic working machinery and medical facilities, need high rigidity, high speed and compact can still ensure accurate situation.
