Measurement of wear in radial journal bearings [PDF]
Tribotest, 1996 AbstractIn this article, the measurement of wear in radial journal bearings is discussed, where a distinction is made between stationary and non‐stationary contact conditions. Starting with Holm/Archard's wear law, equations are derived for the calculation of the specific wear rate k of the bearing material as a function of the wear depth d, measured ...
