Considerations for choosing the correct rolling-element bearing characteristics

02 March 2023

Daily experience in application engineering has proven that the selection of the correct bearing type can be successfully achieved by customers, based on the documentation and tools provided by the bearing manufacturer and using comparable applications as a guideline.

This selection process is typically dominated by two complementary factors. First, the required bearing life rating in the application, as a result of the relation between the bearing’s dynamic load rating, the magnitude and direction(s) of the forces acting, and the speed of rotation. Second, the build size of the bearing in relation to the available space in the application.

In addition, there are several other critical bearing characteristics which are not always considered with the required diligence. These may later cause questions and issues to arise. These are, amongst others: clearance, cage type, lubrication, standard, pre-installed sealing variants in radial deep-groove ball bearings, etc.

The following aims to address these reoccurring questions.
