Care and Maintenance of Bearings - NTN Global
The rolling-contact bearing is an element of machinery with a very important role, and is critical to the performance of the machine. If one of the bearings breaks or seizes, not only the machine but also the assely line may stop. If one of the axle bearings of an automobile or a railway car breaks down, a serious accident could occur.
Ball Bearing Mechanics - NASA
fatigue life of ball bearings is developed in Section 3.5. Ball bearings can be lubried satisfactorily with a small amount of lubricant supplied to the right area within the bearing. Section 3.6 considers the selection of a satisfactory lubricant, as well as describing systems that provide a constant flow of lubricant to the contact.
