Mounted Hydrodynamic Bearings

Motion offers a selection of mounted hydrodynamic bearings from leading brands like Dodge, Timken and Browning.. Mounted hydrodynamic bearings carry loads and support shafts but do not have rolling elements. Also called fluid dynamic bearings, they use a layer of water or oil continuously drawn in by their own motion to reduce friction and carry many tons of weight. Hydrodynamic bearings use a pump to start and stop because dry startups quickly wear down bearings. They are used only in environments with little shock or vibration because shock can disrupt the fluid film and cause the bearing to fail. In an ideal environment, hydrodynamic bearings operate at high speeds and temperatures without wear.
