High speed hybrid bearings for cryogenic applications demand large levels of external
pressurization to provide substantial load capacity. These conditions give rise to large film …

An aerostatic journal micro-bearing has advantages of simple structure, almost zero friction
and increasable load capacity due to aerodynamic pressure effect, which makes it a …

The quality of predictions for the operating behavior of high-speed journal bearings strongly
depends on realistic boundary conditions within the inlet region supplying a mixture of hot …

Flooded lubrication of tilting-pad journal bearings provides safe and robust operation for
many applications due to a completely filled gap at the leading edge of each pad. Direct …

When a cutter traverses a region local to the singularity in 5-axis machining, the stability of
machine tool motion may be violated and inevitably lead to a reduction in machining quality …

Rotation effects of hybrid air journal bearings with multi-arrays of orifice feedings are
investigated numerically. Porous air bearings are also solved for comparison. The results …

Starved lubrication occurs intentionally or unconsciously in many journal bearing
applications. However, the determination of its concrete distribution in a journal bearing is …

Featured Application Power generation systems based on supercritical carbon dioxide.
Abstract Fluid film bearings lubricated with supercritical carbon dioxide (sCO2) eliminate the …

The analysis of actual lubrication problems needs to take into account particularities in flow
caused by kinematic conditions and contact geometry. For hybrid journal bearings lubricated …

Jacking-oil pockets are applied in many journals and thrust bearing applications in order to
provide a hydrostatic oil film force that ensures a wear free run-up following a successful lift …
