With the rapid development and increasing maturity of domestic high-precision processing equipment, more and more high-precision CNC processing equipment such as CNC indexing plates, vertical machining centers, vertical lathes, and grinders are abandoning traditional designs and adopting better cross-cutting designs. Roller bearings. It has the characteristics of high rotation accuracy and speed, large load-bearing capacity, small size, strong rigidity, etc. It has a wide range of uses and has advantages that other bearings cannot match.

Crossed roller bearings are also called crossed roller bearings. The rolling elements generally use cylindrical rollers or tapered rollers that are arranged crosswise on the raceway. The rollers are separated by cages or isolation blocks. This kind of cross The structure of the roller arrangement allows a single bearing to withstand various loads such as axial load, radial load and overturning moment. Compared with traditional structural bearings, the rigidity is increased by 3-4 times. It is suitable for various industrial rotating parts, rotating worktables and other applications.

The structure of crossed cylindrical roller bearings is that the outer ring and inner ring are integral. The rolling elements are cylindrical rollers, arranged vertically at 90° to each other in a V-shaped raceway. The rollers are separated by isolation blocks. This structure allows a single bearing to bear various loads such as axial load, radial load and overturning moment. At the same time, because the outer dimensions are miniaturized to the maximum extent, and the bearings have high rigidity, rotation accuracy, and composite load-bearing capacity, they are most suitable for joints or rotating parts of industrial robots, rotating tables of machining centers, and robot hand rotations.
