Porous journal bearings are made of a porous bush impregnated with oil, acting as an oil reservoir, and so avoiding any external oil supply, for lubricating the contact between a rotating shaft and the stationary bush (or sometimes between a stationary shaft and a rotating bush).

Automotive Bearing Systems—Journal Bearings
2012The principal use for journal bearings in automotive applications is for the crankshaft bearings, piston pin joint, balancer shafts, and crankshafts. These can either be half shells in which a split is required for assembly (e.g., crankshaft bearings) or bushes that can be inserted without a split (e.g., piston pin joints). For engine bearings, the oil

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2002
In this report, numerical analyses of very narrow journal bearings are presented. The pressure distribution was determined for a number of different width-diameter ratios and eccentricities. For each combination, a number of relevant dimensionless design quantities were computed.

Counterrotating Journal Bearings
Journal of Basic Engineering, 1962A theoretical derivation is given showing that whenever the center of curvature of a bearing does not coincide with its center of rotation, synchronous counterrotation will produce a load capacity. Test results are given for a number of bearing designs that operated successfully under synchronous counterrotation with load capacities beyond 1500 psi ...

Pad–Pivot Friction Effect on Nonlinear Response of a Rotor Supported by Tilting-Pad Journal Bearings
Journal of tribology, 2019This paper presents a numerical study for nonlinear rotordynamic response with bifurcations of tilting pad journal bearings when pad–pivot friction forces are taken into account. A Stribeck friction model is employed to determine the friction coefficient
