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, grinders, etc. have abandoned traditional designs and adopted better cross roller bearings. It has the characteristics of high rotation accuracy and speed, large load-bearing capacity, small size, strong rigidity, etc., and has a wide range of uses and advantages that other bearings cannot match. Crossed roller bearings are also called cross roller bearings. The rolling elements generally use cylindrical rollers or tapered rollers to cross and cross each other on the raceway. The rollers are separated by retainers or isolation blocks. This cross-arranged roller structure allows a single bearing to withstand various loads such as axial loads, radial loads and overturning moments. Compared with traditional structural bearings, the rigidity is increased by 3-4 times. It is suitable for various industrial rotating parts, rotary tables and other applications.
