A method of manufacturing a bearing pin with an external lubrication channel and the bearing pin formed thereby are disclosed. The method includes fixing a rotational orientation of the bearing pin along a pin axis, cutting an outer surface of the bearing pin in a first straight line across a first convex portion thereof to create a first open external groove of the lubrication channel; and cutting an outer surface of the bearing pin in a second straight line across a second convex portion thereof to create a second open external groove of the lubrication channel. The grooves have a concave sectional profile and circumferential open ends disposed intermediate and not intersecting the ends of the bearing pin.

Slide bearings and methods of producing slide bearings are disclosed. The slide bearing has a metal support and a sliding layer. No other layer is in contact with the sliding layer. The sliding layer is applied directly to the metal support. The sliding layer comprises a mixture of at least two polymers P1 and P2, wherein P1 is a fluoropolymer. P2 is a non-fluorinated thermoplastic polymer.

A bearing housing (12) for a turbocharger having a rotatable shaft (14) passing through the bearing housing (12) with journal bearings (30) having tilting pads (40) for supporting the rotatable shaft (14) in the bearing housing (12). The tilting pads (40) may have oil supply holes (50) through each pad (40) to direct lubrication to each pad surface (44). The journal bearings (30) preferably have a circumferential groove (52) on an outer surface of the bearing aligned with the oil supply holes (50) to help feed oil to the oil supply holes (50).

A self-lubricating composite material is disclosed. The self-lubricating composite material can include discontinuous polymer fiber segments dispersed within a woven matrix of semi-continuous thermoplastic fiber. The woven matrix can be embedded within a thermosetting resin. Also disclosed are methods of manufacturing the self-lubricating composite material.

A tilt pad bearing may include a support structure having first and second support structure surfaces. A pivot may have first and second pivot surfaces, and the first pivot surface may be coupled to the second support structure surface. A pad may have first and second pad surfaces, and the first pad surface may be coupled to the second pivot surface. A path of fluid communication may extend from the first support structure surface, through the pivot, and to an opening in the second pad surface.
