such that the centerline 154 of the thrust bearing and the tilt center 118 of the turbocharger are co incident since the axial location of the tilt center 118 is reliant among other features on the position design and tolerancing of the journal bearings and their associated mounting features the bearing centerline 154 by design must be axially placed with those features the radius of curvature of the spherical segments could be freely selected so long as the tilt center is located at the core the radius of curvature is determined by the distance from the tilt center fixed from the geometry to the axial point at which the designer chooses to place the thrust bearing in the bearing housing the thrust capacity of the thrust bearing is handled by the area of the pad and ramp and the ramp depth along with details of the oil supply pads with a large area can support large thrust forces pads with small areas can support small loads if one has a pad with small area and a large force is present the placing of an oil dam at the foot of the ramp supplies a lot of oil which raises the load carrying capacity to a point oil is fed to the thrust ramps through the oil galley 146 in the bearing housing and thence through the oil canal 125 in the thrust bearing in a manner similar to that of a typical thrust bearing details of this design may be freely varied in another embodiment the thrust bearing 150 fig1 is reduced in diameter and the thrust bearing is supported and captured in a holder 155 the holder has a spherical segment surface 161 which mates with another spherical surface.
