深沟球轴承主要承受径向载荷，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。轴承特性深沟球轴承是最具代表性的滚动轴承，用途广泛。适用于高转速甚至极高转速的运行，而且非常耐用，无需经常维护。该类轴承摩擦系数小，极限转速高， 结构简单，制造成本低，易达到较高制造精度。 尺寸范围与形式变化多样，应用在精密仪表、低噪音电机、汽车、摩托车及一般机械等行业，是机械工业中使用最为广泛的一类轴承。主要承受径向负荷，也可承受一定量的轴向负荷。选取较大的径向游隙时轴向承载能力增加，承受纯径向力时接触角为零。有轴向力作用时，接触角大于零。一般采用冲压浪形保持架，车制实体保持架，有时也采用尼龙架。
Deep groove ball bearing is mainly subjected to radial load, it can also bear radial load and axial load at the same time. When it only bears the radial load, the contact angle is zero. When the deep groove ball bearing has larger radial clearance, it has the performance of angular contact bearing, which can bear large axial load. The friction coefficient of deep groove ball bearing is very small, and the limit speed is also very high. Bearing characteristic deep groove ball bearing is the most representative rolling bearing, which is widely used. It is suitable for high speed or even high speed operation, and is very durable, without regular maintenance. This kind of bearing friction coefficient is small, extreme high speed, simple structure, low manufacturing cost, easy to manufacture high precision. It is widely applied in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries. It is the most widely used kind of bearings in the machinery industry. It is mainly subjected to radial load, and can also bear a certain amount of axial load. When the larger radial clearance is selected, the axial bearing capacity increases and the contact angle is zero when the radial force is subjected to pure radial force. When the axial force is acted on, the contact angle is greater than zero. General use of stamping wave shaped cage, car - made solid cage, and sometimes nylon frame.
