这种轴承具有接触角，所以适于承受一个方向的轴向负荷，或合成负荷。结构上，承受径向负荷后产生轴向分离，所以，将2 个轴承对置使用，或二个以上成对双联使用。单列向角接触球轴承，可以使用预压方法提高刚性，因此，适用于高旋转精度的机床主轴等。一般，接触角30°（代号Ａ）及40°（代号Ｂ）的角接触球轴承保持架，依照表1。但根据不同的条件也使用合成树脂保持架或聚酰胺成型保持架。尺寸表记载的基本额定负荷，以表1 保持架区分为基准。

Single-Row Angular Contact Ball Bearings (Pressed Steel Cages & Machined Brass Cages)

Since these bearings have a contact angle, they can sustain significant axial loads in one direction together with radial loads. Because of their design, when a radial load is applied, an axial force component is produced; therefore, two opposed bearings or a combination of more than two must be used.

Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools, for which high running accuracy is required.

Usually, the cages for angular contact ball bearings with a contact angle of 30° (Symbol A) or 40° (Symbol B) are in accordance with Table 1, but depending on the application, machined synthetic resin cages or molded polyamide resin cages are also used. The basic load ratings given in the bearing tables are based on the cage classification listed in Table 1.
