  • Lube-for-life journal bearings
    flatlines. A typical sintered journal bearing develops cracks when subjected to repeated impact loading. Many engineers consider external lubrication systems for journal bearings a necessary evil. The approach adds design complexity and another item to be routinely serviced. Not to mention, liquid
  • Profiled Leading Edge Groove Tilting Pad Journal Bearing for Light Load Operation (.pdf)
    in diameter tilting pad journal bearings. This configuration yielded a design with projected bearing loads of less than 25 psi, and journal surface speeds that could approach 400 ft/sec.
  • Pad Temperature in Tilting Pad Journal Bearing Influenced by Operation at High Speed and Light Loads (.pdf)
    The trend towards higher speed for increased aerodynamic performance of turbomachinery has aroused much interest in the subject of bearing influenced rotordynamics. A major contribution to this was the development of the variable geometry tilting pad journal bearing. The inherent stability
  • Optimization of a Leading Edge Groove Tilting Pad Journal Bearing for Application in a Small, High Speed Multi-Stage Steam Turbine (.pdf)
    in. diameter tilting pod journal bearings. This configuration yielded a design with projected bearing loads of less than 25 psi, and journal surface speeds that could approach 400 ft./sec. Under these conditions, the applicable limits of conventional style tilting pad journal bearings are stretched
  • Hydrostatic Bearings
    Designing hydrostatic bearings is more complex than for self-acting types because of the greater number of components requiring design decisions. The pressure pads in hydrostatic bearings carry the load. Most hydrostatic systems (thrust or journal bearings) use several evenly spaced pads so
  • Hydrodynamic Bearings
    be considered when selecting bearing materials. Bearings subjected to cyclic stresses can fail by fatigue. The bearing material should also be compatible with the journal material so when metal-to-metal contact occurs at starting and stopping, minimal surface damage occurs. Hydrodynamic instability occurs when
  • Ceramic Ball Bearings
    but bearing life will be compromised and for. these applications journal bearings provide a more robust solution.
  • Design bearings that don't seize
    properly reaching bearings can trigger TIS, including a clogged oil filter. Bearings starved of lubricant generate excessive frictional heat. For example, a hydrodynamic journal bearing with a full film of lubricant separating surfaces typically has a friction coefficient, of about 0.001 to 0.008
