Angular contact ball bearings can support radial load and axial load can also be subject to pure axial load, can operate at higher speeds. Single row angular contact ball bearings can withstand a direction of the axial load, axial load capacity by the contact angle, contact angle, high axial load capacity, but smaller the contact angle is more conducive to high-speed rotation. The contact angle α is defined as the angle of the ball and raceway contact line and line with the bearing axis perpendicular to the radial plane connection between. Press contact angle is divided into:
1, contact angle α = 15 °, post code is C, and more for larger size precision bearings, such as 7005C;
2, the contact angle α = 25 °, post code for AC or A5, used for precision spindle bearings, such as 7005AC;
3, the contact angle α = 30 °, post code for A, used for precision spindle bearings, such as 7005A;
4, the contact angle α = 40 °, post code is B, applicable to withstand large axial load, such as 7005B;
