What is a thin section angular contact ball bearing?

Characteristics of thin section angular contact ball bearings

The contact angle of thin section angular contact ball bearings is defined as the angle between the load-bearing line and the radial plane. The contact angle can be divided into 15 ° (code: C), 25 ° (code: AC), 30 ° (code: A), and 40 ° (code: B). The larger the contact angle, the higher the ability to carry axial loads under the same size.

Thin section angular contact ball bearings, while bearing pure radial loads, generate internal bearing forces due to the fact that the load line of the dry rolling element is not in the same radial plane as the radial load line. Therefore, most angular contact ball bearings are installed in pairs, with each other tightly bedded to achieve axial separation and improve the axial stiffness of the entire component. The main assembly methods include back-to-back (DB), face-to-face (DF), and series (DT) installation.

Characteristics of thin section  angular contact bearings

Its characteristic is its high axial bearing capacity.

The difference between thin section angular contact ball bearings, thin section deep groove ball bearings, and thin section four point contact ball bearings lies in the shape of their grooves. thin sectionangular contact ball bearings (Type A) have angular contact between the raceway and the ball. The center of the raceway radius deviates from the centerline of the steel ball and is symmetrically distributed based on the centerline.

The difference between thin section equal section angular contact ball bearing and standard angular contact ball bearing is that its section size is designed as a single one, and its section size and standard size are unchanged in a series. It does not increase with the increase of pore size. Therefore, this type of thin bearing is called a constant cross-section thin bearing. By using thin bearings from the same series throughout the entire product range, designers can standardize universal components.
