Double-row Angular contact ball bearings
The angular contact ball bearing is mainly divided into single row angular contact ball bearing, double row angular contact ball bearing and four point contact ball bearing .It can bear radial and axial roads at the same time and can bear pure axial load as well with higher limiting speeds .The capability of bearing axial load is determined by the degree of contact angle, The bigger the contact angle, the bigger the axial load can be borne. The contact angles are classified as 15º、25º、40º.When the bearing bears radial load, additional axial force will mount in pairs, there are three kinds of installment namely ,back-to-back ,face-to-face and in series.
When the contact angle for the double row angular contact ball bearing is 30º, it can bear bigger radial and axial bidirectional combined loads and moment load with radial load in the main. The bearing is mainly used in the units for restriction of bidirectional axial displacement of shaft or housing .Double row angular contact ball bearing are divided into two structures-one outer ring with two inner rings and two outer rings with one inner ring.
 ▲   The design’s of all these angular contact ball bearings are based on standard structures; LYNB can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and mounting dimensions that are required. Please contact the LYNB Technical Center if you need any assistance in this area.
