Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Slip couplings, e.g. slipping on overload, for absorbing shock > of the ratchet type > with intermediate balls or rollers

CPC:

Slip couplings, e.g. slipping on overload, for absorbing shock (combined with yielding shaft couplings F16D3/14; fluid slip couplings F16D31/00 - F16D35/00) > of the ratchet type (similar gearings based on repeated accumulation and delivery of inertia-energy F16H33/08; ) > with intermediate balls or rollers

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

IPC defines codes here since 1990.
