LUBRICATING

Introduced: September 1968

Description

F16N covers systems, methods, and devices for lubricating mechanical machinery and components to reduce friction and wear. This subclass encompasses lubricant application techniques, lubrication circuits, automatic lubrication systems, and related mechanical arrangements designed to deliver lubricants to moving parts in engines, transmissions, bearings, and industrial equipment. The classification includes both manual and automated lubrication mechanisms but excludes the chemical composition of lubricants themselves, which are addressed in C10M.

Of 28 combined children, 21 exist in both systems.

7 codes are CPC-only extensions.

Note: 7 CPC extensions are marked as secondary classification only.

12 shared codes have differing titles between IPC and CPC.
