Oil Film Bearing

Oil film bearings are the core transmission components of modern rolling mill equipment. They form a micron-level oil film between the journal and the bearing sleeve through the principle of hydrodynamic lubrication, achieving stable operation under heavy-load and high-speed working conditions.
