According to the working principle of bearing, it can be divided into rolling friction bearing (rolling bearing) and sliding friction bearing (sliding bearing).

滑动轴承:在滑动轴承表面若能形成润滑膜将运动副表面分开，则滑动摩擦力可大大降低，由于运动副表面不直接接触，因此也避免了磨损。滑动轴承的承载能力大，回转精度高，润滑膜具有抗冲击作用，因此，在工程上获得广泛的应用。

Sliding bearing: if a lubricating film can be formed on the surface of the sliding bearing to separate the surface of the moving pair, the sliding friction can be greatly reduced. Since the surface of the moving pair is not in direct contact, wear is also avoided. Sliding bearing has large bearing capacity, high rotation precision and anti impact effect of lubricating film. Therefore, it has been widely used in engineering.

润滑膜的形成是滑动轴承能正常工作的基本条件，影响润滑膜形成的因素有润滑方式、运动副相对运动速度、润滑剂的物理性质和运动副表面的粗糙度等。滑动轴承的设计应根据轴承的工作条件，确定轴承的结构类型、选择润滑剂和润滑方法及确定轴承的几何参数。

The formation of lubricating film is the basic condition for the normal operation of sliding bearing. The factors affecting the formation of lubricating film include lubrication mode, relative motion speed of moving pair, physical properties of lubricant and surface roughness of moving pair. The design of sliding bearing shall determine the structural type of bearing, select lubricant and lubrication method and determine the geometric parameters of bearing according to the working conditions of bearing.
