Abstract

Bearings are considered critical elements during machine operation, and can present different failure modes, which are divided into six categories according to ISO 15243:2004. The present work aims to discuss corrosion, lubrication and their impacts on the life of bearings and on the types of failure modes in bearings. For the elaboration of this work, a methodology of the bibliographical research type was applied in articles of similar subjects. Through this work, the main types of failures in bearings will be shown, with the aim of helping to identify potential and/or functional failures, allowing their efficient application in different types of segments. The results help in the quick identification, providing agility in taking actions. Through the application of concepts of corrosion, lubrication and fracture, it was concluded that the identification of failure modes in bearing supported by ISO classification and visual manifestations of damage in more common bearings that help to determine the type of dominant wear.
