Angular contact ball bearings

Angular contact ball bearings have a high limit speed, can bear radial load and axial load at the same time, and can also bear pure axial load. The axial load bearing capacity is determined by the contact angle and increases with the increase of the contact angle.
Single row angular contact ball bearings: 718, 719, 70, 72
Single row angular contact ball bearings often need to be matched with other bearings that are subjected to reverse axial loads. That is to say, angular contact ball bearings are usually used in duplex, triple, quadruple or even quintuple combinations.
The contact angle of precision angular contact ball bearings is divided into 15° (code C) and 25° (code AC). For angular contact ball bearings, the larger the contact angle, the greater the axial load capacity, but the limit speed of the bearing is lower. Therefore, a bearing with a contact angle of 15° should be used for the spindle support with high rotational speed and small axial load, otherwise, an angular contact ball bearing with a contact angle of 25° should be used.
Double row angular contact ball bearings: 2344, 2347 series bearings
Two-way thrust contact ball bearings consist of two shaft washers, a seat washer, a spacer, and two rows of rolling element and cage assemblies. The bearing has a contact angle of 60° and does not carry radial loads，have the advantages of high precision, good rigidity, low temperature rise, high rotation speed, and convenient loading and unloading.
