That portion of a rotating piece, as a shaft, axle, spindle, etc., which turns in a bearing or box. See Illust. of Axle box.

That part of a shaft that is in contact with, and supported by, a bearing.

That part of a rotating shaft supported by a bearing.

A round section of shaft

The polished surface on either the crankshaft or cam in which the bearings rub. The crankshaft has both main journals and rod journals. The cam has only bearing journals.

The bearing surface within which a shaft operates.

The end of a railroad car or locomotive axle that actually serves or rides-in the bearing that supports the load.

the part of the axle contained by a bearing

the part of an axle which bears the weight. It fits into the "bearing" part of the truck.

That part of a shaft that is prepared to accept and support a bearing. The area on the crankshaft that fits into the lower portion of the connecting rod. A layer of oil and metal bering cushions the impact during the power stroke to prevent the crankshaft from being crushed by the swiftly descending piston and connecting rod. Also see camshaft journal crankshaft journal

Specific portions of the shaft surface from which rotor applied loads are transmitted to bearing supports.

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

A journal is that part of a rotor that is in contact with or supported by a bearing in which it revolves.

The area on the crankshaft that fits into the lower portion of the connecting rod. A layer of oil and metal bearings cushions the movement of the connecting rod around the journal to prevent premature wear.

That part of a shaft or axle which rests on the bearings.

That part of an axle which rotates inside an axle-box and thus forms the bearing surface.

1. A record of current transactions. 2. A log. 3. The part of a rotating shaft, axle, roll, or spindle that turns in a bearing.

Rotary axle or shaft portion, which turns in a bearing.

In mechanics, a journal is the section of a rotating shaft (such as an axle, driveshaft, or spindle) that contacts and turns in a bearing. In automotive engineering, the term journal specifically describes the connection between the crankshaft and the main bearings (as opposed to the connection between the crankshaft and the connecting rod bearings). Journal & Bush bearings are same one.
