What is a bearing

Send your inquiry

Definition of bearing: A bearing is a part that supports the shaft. It can guide the rotation of the shaft and can also bear the idling parts on the shaft. The concept of the bearing is very broad. Bearings can be divided into rolling bearings and sliding bearings. The most common bearings are rolling bearings. Bearings with rolling elements are classified as rolling bearings; sliding bearings generally refer to bearings without rolling elements, and bearings for sliding motion are all sliding bearings.

The classification of rolling bearings is mainly classified according to the shape of rolling elements, bearing force and structural type. The structure of rolling bearings generally consists of inner rings, outer rings, rolling elements and cages. See the figure below, which indicates the name of each component of the bearing.

The above figure lists only the three most common and commonly used single-row rolling bearings. According to the number of rolling elements, the bearings can also be divided into double-row and multi-row bearings. Two or more rows of rolling elements are installed in the same set of bearings. A number of rolling bodies are installed between the bearing rings or the shaft and seat rings, and the rolling bodies are evenly spaced by the cage, which prevents the rolling bodies from colliding with each other, so as to reduce the resistance so that the bearing can reach a higher speed.

The classification of rolling bearings is also classified according to the direction of bearing load and force of the bearing. The angle formed between the direction of the load between the rolling surface of the bearing ring and the rolling element and the plane perpendicular to the centerline of the bearing is called the contact angle. When the contact angle When the contact angle is less than 45°, the bearing mainly carries radial force, it is called a radial bearing; when the contact angle is between 45° and 90°, it is called a thrust bearing. See the figure below for radial and axial directions:

The classification of sliding bearings is mainly divided into joint bearings and dry sliding bearings. Joint bearings are divided into centripetal joints, thrust joints, rod end joint devices, etc., which are divided into two categories: lubricating and self-lubricating. Dry sliding bearings are divided into dry sliding bushings, sliding gaskets, linear sliding bars and other series. Classification diagram of sliding bearings
