SKF bearing selection

When selecting SKF bearings for any purpose, ultimately you want to be certain of achieving the required level of equipment performance, and robustness, at the lowest possible cost. There are key factors you must consider when selecting SKF bearings for an application. For helping you evaluate these key factors, we provide recommended SKF bearing selection, as well as supporting information.

SKF general bearing knowledge:

SKF bearing selection

In addition to the SKF bearing rating life, there are key factors you must consider when putting together the SKF bearing specifications for an application, including:

  • lubricant and supply method
  • shaft and housing fits
  • bearing clearance class
  • cage material and guidance
  • dimensional stability
  • precision requirements
  • bearing sealing 
  • mounting method and maintenance

To help evaluate there key factors, we recommend following this selection process:

The SKF bearing selection provides a straight forward step-by-step approach that shows the general relationship between each step.

1, Performance and operating conditions.

The first step of SKF bearing selection is to understand and document:

  • the required performance
  • the operating conditions and assumptions of them
  • any other application prerequisites

The drawing shows the relationship between principal operating conditions, application requirements and various aspects of a bearing arrangement’s design. The lists are not comprehensive and you may have to consider other factors and interrelationships, such as cost and availability, when striving to obtain a robust and cost-effective solution.

2, SKF bearing type and arrangement

Each SKF bearing type has characteristic properties that make it more or less suitable for use in a given application. This section provides information on what to consider when selecting a bearing arrangement and the types of bearing to use with it. It also provides guidelines on choosing bearing types to satisfy specific demands of an application, such as accommodating available space, loads, misalignment, and more.
