Bearing Lubrication Tips & Mistakes You Might Be Making

WebJun 13, 2024 · Rotor-bearing systems often rely on squeeze film dampers to increase the dynamic stability and reduce rotor motion amplitudes while traversing critical speeds. In aircraft engines, to increase the damping capacity within a limited physical space, piston rings seal the axial ends of a squeeze film land. Alas, lubricant still leaks through the slit … Webbearing to be more closely matched. This results in a broader oil film that spreads the load over more of the bearing surface, thus reducing the pressure within the oil film and on the bearing surface. This will in turn improve bearing life and performance. Typically, a used bearing should exhibit signs of use over 2/3 to 3/4 of its ID surface ... resounding silence
