The article is devoted to the study of the influence of the lubricant properties on the life of a rolling bearing. This effect is studied with the help of the system resource modification coefficient. The choice of lubricant must be carried out taking into account the specific operating conditions of the bearing, which will further clarify the service life of the bearing. The article analyzes the revealed dependences of the value of the system coefficient of resource modification on the properties of the lubricant. Dependencies are given for calculating the modified resource, the system resource modification coefficient of a rolling bearing. An example of choosing a grade of oil for rolling bearings is presented.
