The main task of service life analysis of spherical roller bearings is to find out the main factors causing bearing failure according to a large number of background materials, analysis data and failure forms, so as to put forward targeted improvement measures, extend the service life of bearings, and avoid the sudden early failure of spherical roller bearings.

The method of installing spherical roller bearings depends on the bearing fit, condition and structure. Generally, because it is mostly shaft rotation, the inner ring needs interference fit. Cylindrical bore bearing, multi-purpose press into, or multi-purpose hot charging method. The taper hole is installed directly on the taper shaft, or installed with a sleeve.

Wear failure refers to the failure caused by the continuous wear of metal on the working surface caused by the relative sliding friction between surfaces. Continuous wear will cause gradual damage to spherical roller bearing parts, and ultimately lead to loss of bearing dimensional accuracy and other related problems. Wear may affect the shape change, the increase of fit clearance and the change of working surface topography, may affect the lubricant or make it pollute to a certain extent, resulting in the complete loss of lubrication function, so that the bearing loses the rotation accuracy and even cannot operate normally. Wear failure is one of the common failure modes of all kinds of bearings, which can be divided into the most common abrasive wear and adhesive wear according to the wear form.
