Abstract
A ball bearing system for use with engine turbochargers dampens axial and radial thrust loads of a turbocharger and enhances performance and longevity. The system includes a bearing carrier with an aperture to house a shaft having a compressor wheel affixed to a first end of the shaft and a turbine wheel affixed to a second end of the shaft, the bearing carrier being able to house a plurality of bearings in contact with the shaft, an outer housing member connected to the shaft to enclose the bearing carrier, and a first O-ring and a second O-ring both disposed within grooves around the outer surface area of the bearing carrier, each O-ring also in contact with a corresponding groove in the interior of the outer housing member. The O-rings dampen the axial and radial loads of the rotating shaft of the turbocharger.
