Word of the Day 2 September 2026

journal

the part of a rotating shaft or axle that rests on the bearing

Why this one

Nothing to do with writing. It is the surface that decides whether a bearing survives, and one of the most misread words in machinery.

In use

Mic it up before you order shells, because if that journal's worn oval no new bearing is going to hold oil pressure.

Written by our editors to show how the term is used, not a recorded quotation.
