|When radial ball bearings rotate, the inner and outer rings and rolling elements are constantly loaded. This produces material fatigue and eventually bearing failure, and the total number of revolutions before a failure occurs is called the basic rating life.
Understanding the published load ratings is an integral consideration when choosing a bearing, and this white paper breaks down the methods used to calculate ratings, which can vary between manufacturers.
Choosing the Correct Bearing Materials by AST Bearings
Choosing the correct bearing is an instrumental decision for ensuring the ideal performance of your unique application. One integral subset of this choice is selecting the appropriate bearing materials. The scope of options can be overwhelming – ceramics, chrome steels, stainless steels, plastics – but understanding the benefits and limitations of each is vital in achieving maximize bearing performance and life.
This white paper by AST Bearings examines weight, strength, hardness, noise, corrosion, temperature and price considerations when choosing a bearing.
