Related Terms

CLEARANCE BEARING

A journal bearing in which the radius of the bearing surface is greater than the radius of the journal surface.

JOURNAL FRICTION

Friction of the axle in a journal bearing arising mainly from viscous sliding friction between journal and lubricant.

OIL LIFT

Hydrostatic lubrication of a journal bearing by using oil at high pressure in the area between the bottom of the journal and the bearing itself so that the shaft is raised and supported by an oil film whether it is rotating or not.

JOURNAL BEARING

A sliding type of bearing having either rotating or oscillatory motion and in conjunction with which a journal operates. In a full or sleeve type journal bearing, the bearing surface is 360° in extent. In a partial bearing, the bearing surface is less than 360° in extent, i.e., 150°, 120°, etc.

FULL JOURNAL BEARING

A journal bearing that surrounds the journal by a full 360°.

THRUST-RADIAL BEARING

This unit has the ends of the babbitt bearing extended radially over the end of the shell. Collars on the rotor face these thrust pads, and the journal is supported in the bearing between the thrust collars.

OIL RING

A loose ring, the inner surface of which rides a shaft or journal and dips into a reservoir of lubricant from which it carries the lubricant to the top of a bearing by its rotation with the shaft.

GAS BEARING

A journal or thrust bearing lubricated with gas. Also known as gas lubricated bearing.

SLEEVE BEARING

A journal bearing, usually a full journal bearing.

JOURNAL

That part of a shaft or axle that rotates or angularly oscillates in or against a bearing or about which a bearing rotates or angularly oscillates.
