ABSTRACT:
A hybrid bearing for a horizontal rotatable shaft includes an upper portion which is essentially a half section of a fixed arc journal bearing. The lower portion of the bearing is essentially the lower portion of a tilting pad bearing. Appropriate modifications are made to the oil film and drain lines and other peripheral elements to accommodate the hybrid nature of the bearing. The resultant bearing has the low power loss characteristics of the journal bearing, and additionally, the stability characteristics of a tilting pad bearing.
