Abstract

There is disclosed a bearing (10) to support a rotating shaft (5). The bearing (10) includes a cylindrical housing (20) defining a central opening (22). A plurality of bearing pads (40) integrally coupled to the housing (20) with each bearing pad having a circumferential surface (42) defining a portion of the central opening. A plurality of pins (50) disposed in a bore defined in the housing, with each pin (50) aligned as a pivot for each corresponding pad (40). Each pad (40) can tilt about the pin (50) in relation to the rotating shaft (5). Each pad (40) is coupled to the housing (20) by a pair of webs (44) defined by a plurality of cuts (28) forming a plurality of openings in the housing substantially parallel to a line tangent with the circumferential surface of the pad (40). Each pin (50) is aligned parallel with the rotating pad (40).
