Abstract
A double sided 360° thrust bearing having oppositely oriented interlocking elements each with an open segment and an elevated segment is assembled over a thrust collar on the shaft interconnecting the turbine wheel and compressor wheel of a turbocharger. Bearing pads on the front surface and rear surface of the mated interlocking elements and on the oppositely oriented elevated segments engage reaction surfaces in a channel on the thrust collar. Lubrication channels in the mating faces of the interlocking elements provide oil to the bearing pads on the front and rear surfaces of the bearing while interconnecting lubrication conduits provide oil to the bearing pads on the elevated segments.
