Apparatus for detecting degradation of the lubrication conditions of smooth bearings connecting a crank shaft to a connecting rod or connecting the crank shaft to the body of a machine that reciprocates in operation, lubrication being provided by oil circulation, the apparatus including means for detecting the phenomenon of seizure, wherein the apparatus comprises an additional bearing serving as a test bearing, said test bearing being lubricated by circulation of the same oil as is used for the other bearings and supporting a radially-loaded rotating shaft, said detection means being fitted to the test bearing which also includes means enabling it to be more sensitive than the other bearings to degraded lubrication conditions.
