Angular contact ball bearings

ball bearing

Angular contact ball bearings are suitable for high-speed and high-precision rotation due to their contact angle, and can withstand combined loads.
The standard contact angles are 15 degrees (C), 30 degrees (A), and 40 degrees (B). The larger the contact angle, the greater the axial load capacity; the smaller the contact angle, the more suitable for high-speed rotation.
DB means two combined angular contact bearings.
