LEG Journal Bearings

Leading Edge Groove (LEG) lubrication technology has revolutionized the hydrodynamic bearing industry since 1984 and continues to be our premier directed lubrication bearing technology. The patented LEG journal bearing, in conjunction with our LEG thrust bearing, has made it possible for the worldâs leading equipment manufacturers to increase bearing loads, reduce friction and hold babbitt temperatures within acceptable limits.

Standard LEG tilting pad journal bearings consist of five babbitted journal shoes supported in a precisely machined aligning ring. The back of the journal pad or pivot insert is contoured so that the shoe can tilt and pivot to develop an optimum oil film and self-align to the journal. Kingsbury tilting pad journal bearings are also designed to withstand high shock load or vibration applications.

Key benefits of kingsbury LEG journal bearings are:
  • Reduced operating temperatures
  • Increased load capacity of 15% to 35%
  • 50% lower oil flow rates with an accompanying reduction in power losses of 30 to 50% depending on speed
