深沟球轴承介绍：

深沟球轴承是应用最广泛 的一种滚动轴承，结构简单、使用方便。基本型的深沟球轴承由一个外圈，一个内圈、一组钢球和一组保持架构成。其特点是摩擦阻力小，转速高，除径向载荷外，还可以应用两个方向的轴向载荷。它广泛应用于自行车、摩托车、电机、家用电器等。

Deep groove ball bearing is the most widely used rolling bearing, with simple structure and convenient use. The basic deep groove ball bearing is composed of an outer ring, an inner ring, a group of steel balls and a group of retaining frames. It is characterized by low friction resistance and high speed. In addition to radial loads, axial loads in two directions can also be applied. It is widely used in bicycles, motorcycles, motors, household appliances, etc.
