    Understanding Journal Bearings EDGE

    While the stiffness and damping provided by a journal bearing are crucial, there are other design factors that must be considered in order to understand how bearings work. For example, if the eccentricity is too high there is a risk of metal-to-metal contact and higher dynamic loads being imparted to the babbitt causing premature fatigue.
