Angular contact ball bearing

Angular contact ball bearings can withstand both radial and axial loads simultaneously. Capable of operating at higher speeds. The larger the contact angle, the higher the axial bearing capacity. The contact angle is the angle between the contact point line between the ball and raceway in the radial plane and the vertical line of the bearing axis. High precision and high-speed bearings typically have a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase. Angular contact ball bearings have raceways on both the inner and outer rings, and the inner and outer rings can move relative along the bearing axis. This type of bearing is particularly suitable for bearing composite loads, i.e. loads acting both radially and axially. The axial load bearing capacity of angular contact ball bearings varies with the contact angle α And increase with the increase of. The contact angle is the angle between the contact point line between the ball and raceway in the radial plane and the vertical line of the bearing axis. The accuracy level of angular contact ball bearings includes dimensional tolerance and rotational accuracy. The accuracy is represented as P0 (normal), P6 (P6X), P5, P4, P2 from low to high. In addition, P3, P7, and P9 are also used in European and American brands to represent accuracy levels. P3 is equivalent to P6 in ISO and JIS standards, P7 is equivalent to P4, and P9 is equivalent to P2. High speed precision angular contact ball bearings are mainly used in high-speed rotating situations with light loads, requiring high precision, high speed, low temperature rise and low vibration, and a certain service life of the bearings. Commonly used as a pair of supporting components for high-speed electric spindles, it is a key accessory for high-speed electric spindles in internal surface grinding machines.
