Abstract

A turbocharger has a main housing (12) with a throughbore through which a tubular bearing carrier (40) is coaxially positioned. A shaft (14) extends through the bearing carrier (40) and is rotatably secured to the bearing carrier by a pair of axially spaced bearing assemblies (48, 50), each having an inner race (58, 60), an outer race (74, 80) and bearing elements entrapped therebetween. A pair of spacers (70, 76) are coaxially positioned around the shaft between the bearing assemblies so that an outer axial end (72, 78) of each spacer abuts against the outer race of each bearing assembly. A helical compression spring (86) in a state of compression urges the spacers (70, 76) axially away from each other to equalise the axial compressive load on each bearing assembly and thereby minimise bearing skidding and uneven wear. <IMAGE>
