  • Patent number: 4043612
    Abstract: A spiral-groove self-pressurizing bearing structure is provided with a magnetic lubricant and magnetic means to retain the lubricant in the bearing at rest. During operation, the spiral grooves pressurize and distribute the lubricant within the bearing structure, and the magnetic retention means prevents entrainment of air into the bearing, and consequent loss of lubricating action.
