Cross Roller Slewing Bearing
Crossed roller bearings feature a 90° rolling element arrangement, handling axial, radial, and moment loads with precision and rigidity.
- Compact and low-friction
- they excel in industrial robots
- machine tools and precision instruments ensuring reliable performance in demanding applications.
Structural features
Crossed roller bearings are a kind of rolling bearings with a special structure.
The rollers of the crossed roller bearings are arranged crosswise, and the angle between adjacent rollers is usually 90 degrees. This special structure enables the bearing to bear radial load, axial load and moment load at the same time. Compared with traditional ball bearings or cylindrical roller bearings, crossed roller bearings have higher rigidity and load-bearing capacity.
Advantages
High rigidity: Due to the cross arrangement of rollers, the rigidity of the bearing is very high and can withstand large loads and deformation.
High precision: The manufacturing precision of the crossed roller bearing is high, which can ensure the rotation accuracy and movement stability.
Space saving: The structure of the crossed roller bearing is compact and occupies little space, which is suitable for occasions with limited space.
Strong load-bearing capacity: It can withstand large radial, axial and moment loads, and is suitable for various heavy machinery and high-precision equipment.
Application field
Industrial robots:
- Crossed roller bearings are widely used in the joints of industrial robots, such as arms and wrists, which can ensure the high-precision movement and high load-bearing capacity of robots.
CNC machine tools:
- used in the spindle, lead screw and other parts of CNC machine tools to improve the processing accuracy and efficiency of machine tools.high-strength steel materials
- The surface is usually heat-treated or chrome-plated to increase hardness and wear resistance.
Medical equipment:
- In medical equipment, cross roller bearings can be used for precision instruments and equipment, such as CT machines, MRI machines, etc.
Aerospace:
- Suitable for various equipment in the aerospace field, such as aircraft engines, satellites, etc., and can withstand extreme working conditions and high loads.
In short, cross roller bearings play an important role in many fields with their unique structure and excellent performance.
