7210 CTP4SUL Angular Contact Ball Bearing

angular contact ball bearings can bear radial load and axial load at the same time. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. The contact angle is the angle between the line connecting the contact points of the ball and the raceway in the radial plane and a line perpendicular to the bearing axis. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase.

Single row angular contact ball bearings：7000C, 7000AC, 7000A, 7000B

Combined angular contact ball bearing：Face to face (DB), back to back (DF), tandem (DT), triple

Double row angular contact ball bearings

Four point contact ball bearing：QJ0000, QJF0000

Angular contact ball bearing uses: aircraft engine spindle, machine tool spindle and other high-speed precision mechanical spindles. Also used in high frequency motors, gas turbines, oil pumps, air compressors, printing machinery, etc.
