Practical experience in operation and profound knowledge of the behaviour of machines and machine components has led SKF to develop mechanical condition monitoring methods known as MCM^TM.

The different modules of the MCM^TM series are based on two of the most efficient techniques. The first, the vibrational velocity effective value, is an excellent parameter for evaluating malfunction. By recording the cumulative vibration value of a machine or a component and then comparing the result with the machine reference value, it is possible to spot changes in the machine condition.

The second technique is based on the vibrational enveloping curve and permits the detection of high-frequency malfunctions such as defects of rolling bearings and tooth flanks in gear units.

Parallel application of both methods with one sensor signal makes condition monitoring a comprehensive, efficient operation.
