Just as other mechanical components, roller bearings can also undergo premature failure or housing defects for various reasons. One must differentiate bearing durability determined by loan fatigue during operating speeds and bearing service life, which determines the bearing uptime, before a bearing is for various reasons decommissioned.

The bearing operates in a hummer crusher, thus the vibration signal acquired on the housing contains a lot of impacts that originate in various sources. In the case of local damage detection it

Jaw crusher bearing monitoring with SPM HD Mining operations include a number of critical applications which may cause severe disruptions in the production process in case of malfunctions. One such piece of equipment is the jaw crusher.

Motor bearing damage detection using stator current monitoring Abstract: This paper addresses the application of motor current spectral analysis for the detection of rollingelement bearing damage in induction machines. Vibration monitoring of mechanical bearing frequencies is currently used to detect the presence of a fault condition.

been replaced, but the cause of damage has not been rectified. Due to the high level of complexity of the interaction between the individual components of a bearing inside the engine (see Fig.), the cause of damage is generally not easy to recognise. This is frequently not to be found in the bearing itself, but in the surroundings of the bearing.
