Crossed Roller Bearings

With the rapid development and maturity of domestic high-precision processing equipment, more and more high-precision CNC processing equipment such as CNC indexing discs, vertical machining centers, vertical lathes, and grinding machines are abandoning traditional designs and adopting better crossovers. roller bearings. It has the characteristics of high rotation accuracy and speed, large bearing capacity, small external size, strong rigidity, etc. It has a wide range of uses and incomparable advantages compared with other bearings. Crossed roller bearings are also called crossed roller bearings. The rolling elements generally adopt cylindrical rollers or tapered rollers arranged crosswise on a single raceway. The rollers are separated by cages or spacers. The structure of cross-arranged rollers enables a single bearing to withstand various loads such as axial load, radial load and overturning moment. Compared with traditional structure bearings, the rigidity is increased by 3-4 times. At the same time, the outer dimensions of this series of bearings are miniaturized to the greatest extent. The special ultra-thin structure is close to the limit of miniaturization and has high rigidity, so it is most suitable for the joints of industrial robots.
