深沟球轴承是滚动轴承中最为普通的一种类型。主要承受径向载荷，也可同时承受径向载荷和轴向载荷。当其仅承受径向载荷时，接触角为零。当深沟球轴承具有较大的径向游隙时，具有角接触轴承的性能，可承受较大的轴向载荷 ，深沟球轴承的摩擦系数很小，极限转速也很高。

Deep groove ball bearing is one of the most common types of rolling bearing. Mainly bear radial load, also can bear radial load and axial load at the same time. When its only bear radial load, the contact Angle is zero. When deep groove ball bearings with larger radial clearance, with the performance of angular contact bearings, can withstand large axial load, deep groove ball bearing friction coefficient is small, the limit rotational speed is high.

深沟球轴承主要用于承受径向载荷，也可承受一定的轴向载荷。

Deep groove ball bearing is mainly used to bear radial load, also can absorb a certain amount of axial load.

　　当轴承的径向游隙增大时，具有角接触球轴承的性质，可承受两个方向交变的轴向载荷。

When bearing radial clearance increases, has the properties of Angle contact ball bearing, can carry alternating axial load in two direction.

　　与尺寸相同的其它类型轴承相比，该类轴承摩擦系数小，极限转速高，精度高，是用户选型时首选的轴承类型。

Compared with other kinds of bearings of the same size, such bearing small friction coefficient, extreme high speed, high precision, is a user selection of the preferred type of bearing.

　　深沟球轴承结构简单，使用方便，是生产批量最大，应用范围最广的一类轴承。

Deep groove ball bearing has simple structure, easy to use, is the production batch is the largest, the most widely application scope of a class of bearings.
