    Petropedia - What is a Journal Bearing? - Definition from

    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.

    Three main journal bearing types, their selection

    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.
