Angular contact ball bearings are high-precision rolling bearings that can bear both radial and axial loads, and are particularly suitable for high-speed rotation and high-rigidity support applications. Its design features are that the inner and outer raceways have a relative contact angle (usually 15°, 25°, 30° or 40°). The larger the angle that can transfer load, the stronger the ability to bear axial loads.Angular contact ball bearings are one of the general rolling bearings and are widely used in high-precision, high-speed rotating machinery. Angular contact ball bearings can bear radial loads and axial loads at the same time. The size of the contact angle affects its ability to bear axial loads: the larger the contact angle, the greater the ability to bear axial loads. The commonly used contact angles of angular contact ball bearings are 15°, 25° and 40°, and different application scenarios require different contact angles. Angular contact ball bearings can be used alone, in pairs or in combination to obtain higher rated loads and operating stability.
The inner and outer raceways of angular contact ball bearings form a certain angle in the axial direction, namely the “contact angle”, which is usually 15° to 40°. This structure determines that it can withstand radial force and axial force in one direction at the same time, and withstand bidirectional axial load and moment load when installed in pairs. The bearings are divided into single-row type, double-row type, paired combination type, high-speed sealed type, ceramic ball type and other structures, and are widely used in machine tool spindles, motors, aviation, automotive transmission systems and other equipment that require high speed and high precision.
