This paper deals with condition monitoring and failure diagnostics of spherical roller bearing on adapter sleeve running in high technology Chemical industry machines. Two methods have been used: low frequency mechanical vibration (up to 1000 Hz) and high frequency mechanical vibration (up to 16000 Hz) monitoring method and a shock pulse method (SPM, frequency 32000 Hz). Machines have been tested in at free run and fully loaded. Results have been applied to in-crease reliability of diagnostic methods in a case when radial clearances inside a bearing are too small and there is no enough lubricant oil supply to bearings. Radial clearances and relative vibra-tion displacements of rotor shafts have been measured using proximity probes. The low frequency vibration excitation method is not efficient enough in failure diagnostics of bearings in comparison to high frequency and shock pulse methods. Both these methods together are efficient evaluating technical condition of heavy loaded roller bearings. The experiments have been provided with spherical roller bearings on adapter sleeve SKF 22228 CCK/W33 and SKF 22216 CJC 403.
