RB Series Cross Roller Bearings

RB Series Industrial Automation Cross Roller Bearings ID 20mm

With the rapid development and increasing maturity of high-precision processing equipment, more and more high-precision CNC processing equipment such as CNC indexing plates, vertical machining centers, vertical machine tools, and grinders have abandoned traditional designs and adopted better cross roller bearings.
Cross roller bearings are also called cross roller bearings. The rolling elements are generally cylindrical rollers or tapered rollers arranged crosswise on a single raceway. The rollers are separated by retainers or isolation blocks. They have high rotation accuracy, large load capacity, small dimensions, high rotation speed and rigidity. They have a wide range of uses and advantages that other bearings cannot match.
This cross roller structure allows a single bearing to withstand loads in all directions such as axial loads, radial loads, and overturning moments. Compared with traditional structural 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 maximum extent. The special ultra-thin structure is close to the limit of miniaturization and has high rigidity, so it is most suitable for applications such as joints or rotating parts of industrial robots, rotary tables of machining centers, rotating parts of manipulators, precision rotary tables, turrets, medical instruments, etc.
