Commonly used bearings in industrial robots include the following types:
1. Equal-section thin-wall bearings: This type of bearing has equal cross-sectional areas and can withstand radial and axial loads.
2. Cross crossed cylindrical roller bearings: This kind of bearing can withstand radial and axial loads and has high rigidity and high load-bearing capacity.
3. Harmonic reducer bearings: Harmonic reducer bearings are used to transmit motion and power and have the characteristics of high precision, high rigidity and long life.
4. Linear bearings: Linear bearings are used for linear reciprocating motion and have the characteristics of high precision, high rigidity and high load-bearing capacity.
5. Spherical bearings: Spherical bearings are widely used in various mechanical arms, industrial robots and other equipment. They can withstand radial and axial loads and have good sealing performance.
In addition, there are other types of bearings in industrial robots, such as thin-walled cross cylindrical roller bearings, RV reducer bearings and harmonic reducer flexible bearings. These bearings play an important role in industrial robots and can improve the robot's accuracy, rigidity and load-bearing capacity.
