Angular contact ball bearing

can withstand both radial and axial loads. 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 point of the ball and the raceway in the radial plane and the vertical line of the bearing axis. High precision and high speed bearings typically take a 15 degree contact angle. Under the axial force, the contact angle will increase.
