Journal Bearings - an overview | ScienceDirect Topi

The journal bearing forms a natural wedge as seen in Figure 13-8, which is inherent in its design. Figure 13-3 also shows the pressure distribution in the bearing. Fluid-film thickness depends on the mode, lubrication, and application and varies from .0001 to .01 inches (.00254–.254 mm).

Fundamentals of Fluid Film Journal Bearing Operation a

The operational characteristics of a journal bearing can be categorized into steady state and dynamic aspects. Steady state characteristics include a bearing’s load capacity, pad temperature, power loss and the amount of oil required during operation. A bearing’s load capacity is often measured using

Petropedia - What is a Journal Bearing? - Definition fr

A Journal Bearing is a comprehensive kind of bearing that contains a journal or shaft that freely rotates in a support with a shell or metal sleeve. In the bearing there are no rolling elements present. The construction and design of these bearings is very simple but the operation and theory is complicated.

Several different designs of journal bearings are commonly utilized for gearboxes. The designs are all variations of a sliding bearing where a shaft journal slides on a thin film of oil. The design variations utilize different geometries and features in an effort to achieve rotordynamic stability and avoid sub-synchronous vibrations.
