What are the types of bearings? How many more do you know?
There are various types of bearings that can be classified according to different standards. The following are some common types of bearings:
According to different bearing directions or nominal contact angles, it can be divided into:
Radial bearings: mainly used to withstand radial loads, with a nominal contact angle of 0 ° to 45 °.
Thrust bearings: mainly used to withstand axial loads, with a nominal contact angle greater than 45 ° to 90 °. Among them, the nominal contact angle of axial contact bearings is 90 °, and the nominal contact angle of thrust angle contact bearings is greater than 45 ° but less than 90 °.
2. According to the type of rolling element, it is divided into:
Ball bearings: Rolling elements are balls, such as deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, thrust ball bearings, etc.
Roller bearings: The rolling element is a roller, such as tapered roller bearings, cylindrical roller bearings, etc.
According to whether it can adjust the heart, it is divided into:
Self aligning bearings: Bearings with spherical raceways that can adapt to the angular deviation and angular motion between the axis lines of two raceways, such as self-aligning ball bearings, self-aligning roller bearings, etc.
