Product Details
Product structure:
The internal structure of the cross roller bearing adopts rollers arranged perpendicularly at 90 degrees to each other. The structure is compact and can withstand radial loads, bidirectional thrust loads and overturning moments at the same time. At the same time, cross roller bearings have high rigidity, so they are suitable for joints or rotating parts of industrial robots, rotary tables of machining centers, rotating parts of manipulators, precision rotary tables, medical equipment, measuring instruments, IC manufacturing equipment and other equipment. Crossed roller bearings have three structural types: with cage, with spacer and with full complement rollers. The bearings with cage and spacer are suitable for working conditions with small friction torque and high speed, while the bearings with full complement rollers are suitable for working conditions with low speed and heavy load.
Product features:
1、High load carrying capacity: Compared with the traditional cage, the spacer retainer of the cross roller bearing can increase the effective contact length of the roller, thereby greatly improving the load carrying capacity; at the same time, the spacer retainer guides the full length of each roller, which effectively prevents the roller from tilting. In addition, the spacer retainer keeps the load area symmetrically distributed, preventing end-face contact caused by the asymmetry of the load area, reducing friction and wear, and improving bearing life.
2、High precision: The inner or outer ring of the cross roller bearing can be separated, and the bearing gap can be adjusted, so that it can still obtain higher rotation accuracy under load.
3、High stiffness: Compared with double row angular contact ball bearings, cross roller bearings can bear the load in all directions with only one row of crossed cylindrical rollers, greatly reducing the width of the bearing, and meeting the requirements of compact structure. Because the roller is loaded, the stiffness of the cross roller bearings can also be increased by 3-4 times when the rigidity of the installed components remains unchanged.
4、Simple operation: The crossed roller bearing has a divided inner ring or outer ring. After the rollers and the spacer cage are installed, they are fixed together with the other undivided part to prevent separation from each other, so the installation operation is very simple.
