Turbocharger Bearing

Turbocharger bearings are angular contact type bearings. Usually, these bearings use precision silicon nitride ceramic balls, resin cages, high hardness bearing steel rings. These types of bearings rotate six times faster than any other vehicle bearing and can also withstand temperatures up to 400 degrees Celsius. The bearing is designed to be flow cooled by lubricating oil, and the ultimate speed of the turbocharger bearing reaches 150000 rpm. The bearing material must always resist extreme conditions throughout the life of the turbocharger.
