Ball Bearing Mechanics - NA

fatigue life of ball bearings is developed in Section 3.5. Ball bearings can be lubricated 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.

Radial Play - Bearing Internal Clearance | AST Bearin

Contact Angle in a Ball Bearing When ball bearings are axially preloaded a contact angle is established. ... The balance between the benefits of contact angle reducing stress must be weighed against the potential for lubricant failure due to ball slippage. It is not ...

Tutorial of Hertzian Contact Stress Analys

resultant stresses are not of design significance, but in some cases failure can occur. Ball bearings or kinematic mounts that are repeatedly removed and remounted can start to show damage from fatigue caused by the Hertzian stresses. The Hertzian contact stress equations come in two forms, spherical and cylindrical.
