  • Journal Bearings vs. Ball Bearings - What's the

    The piston pin-bore bearing also acts as a form of journal bearing, so do the big-end bearings, covered in Chapters 19 and 20. Journal bearings usually operate in a hydrodynamic regime of lubrication as the generated pressures are low compared with those experienced by ball and rolling element bearings, gears and cam–follower pairs.

  • The nonlinear and ball pass effects of a ball bearing

    A ball bearing is generally assumed as a linear spring in rotor dynamic analysis. In real case, the force equilibrium of the bearing is changed as the relative position, of each ball with respect to the direction of radial force. So, the stiffness of the bearing is also changed and is a function of time and position. In this study, the nonlinear characteristics of a ball bearing are considered ...
