现代涡轮轴承系统可分为两类：流体动力轴承系统和球轴承系统。
流体动力系统使用发动机油来润滑和控制轴的运动，可选择两个全浮动轴颈轴承或一个一体式半浮动轴承。推力轴承也可用于轴向控制。
球轴承系统将轴颈轴承和推力轴承结合在一起，提高了性能，减小了间隙，降低了功率损耗。

According to Garret who is 1st将滚珠轴承引入涡轮增压器后，一些使用加勒特滚珠轴承涡轮增压发动机的专业驾驶员表示，他们感觉就像在驾驶一台正常吸气的大型发动机。
The development of ball bearing turbochargers has been driven by the pursuit of drivability and better emissions.
Bearings work at high temperatures in an exhaust gas turbocharger environment
High speed of 120,000 to 200,000 rpm, or even higher
Smooth operation and small axial movement
Lean oil lubrication during engine start & stop
Applied in performance cars for rapid acceleration and deceleration
Engine oil provides cooling lubrication
Mainstream alloy steel
Special heat treatment enables the bearing to maintain good performance at high temperatures
Double angular contact ball bearings with ceramic balls
PEEK/metal cages to meet different applications
High-precision
保持器
PEEK/Steel Cage, coating available for different application, improved oil-deprived condition performance.
Si3N4 Ceramic ball
Better at wear resistant and high revolution
Special HT for bearing rings
Enables grain refinement, maintains initial accuracy capability.
PEEK/black coating/silver plating cage optional
