READ MOREOverview of double-row angular contact ball bearings
Double-row angular contact ball bearings, as the name implies, are angular contact ball bearings with double-row steel balls. Its design features are that it can simultaneously withstand large radial loads and axial loads acting in two directions, and can effectively limit the bidirectional axial displacement of the shaft or housing. The contact angle of this bearing is usually 30 degrees, which can provide high rigidity and the ability to withstand overturning moments.
Structurally, double-row angular contact ball bearings are similar to single-row angular contact ball bearings, but occupy less axial space and have better performance. According to the different outer diameter sizes, double-row angular contact ball bearings can be divided into multiple types such as type A (outer diameter less than or equal to 90mm), type B (outer diameter greater than 90mm) and type C (reinforced structure). Each type has its own unique design features and application scenarios to meet the needs of different industrial fields.
