Turbocharger Failure Analysis: What Went Wrong and How to Fix It

3/2/2015· The turbocharger rotor assely thrusts back and forth in a turbocharger while the thrust bearing is anchored in a fixed position in the bearing housing relative to the rotor. When boost pressure acts upon the backwall of the compressor wheel it pulls the thrust ring furthest away into the positive side of the turbo’s thrust bearing, and vice-versa for the turbine.

Sliding Bearings - NORGLIDE® - A modular concept

Sliding bearings or also called plain, journal or sleeve bearings are bearings which reduce the friction between two mating components without a rolling element. A sliding bearing provides many benefits, such as low weight, corrosion resistance and noise and vibration reduction. Additionally, it is maintenance-free.

Journal Bearing and Its Classifiion | Mechanical Engineering

The portion of the shaft which is in actual contact with the bearing is known as journal. For every machine and engine, it is necessary to have a provision for the support of rotating shaft. Such support is called bearing. In other words, the shaft must be supported through bearing. Simple bearing has been shown in Figs. 8.11 (a) and 8.11 (b).

Ball Bearings in Turbochargers: Great for Cars. Not So Good for …

In addition, oil flow for ball bearing systems is required to be lower than that of full-floating hydrodynamic bearings. This reduces parasitic drag, which improves turbo lag performance, but the lower oil pressure flowing through the CHRA reduces the amount of heat that can be removed from the shaft by the oil circulating through the engine.
