SPM-111 Bearing Tester works on echo (shock) pulse method. Bearing Tester gives a direct evaluation of the bearing operating condition while it is still running 

Shock pulse method is a widely used technique for condition monitoring of rolling bearing. However, it may cause erroneous diagnosis in the presence of 

Take this opportunity to learn about the Shock Pulse Method directly from the source. This method was invented by SPM Instrument in Sweden in 1969 and has been widely used ever since. Learn about the basics of the method as well as the latest inventions that brought Shock Pulse into the HD era. Takeaways: – What are the advantages of Shock

SPM HD SPM HD® is a patented further development of the Shock Pulse Method (SPM) used for fast, easy, and reliable diagnosis of the operating condition of rolling element bearings. It provides easy-to-understand condition evaluation in a green-yellow-red scale, as well as crystal-clear spectrums and time signals for further analysis. Features

The shock pulse method (SPM) has achieved wide acceptance as a quantitative method for detecting the defects of rolling element bearings. The 

BearingChecker is a portable instrument for fast and easy measurement of bearing condition in preventive maintenance. The instrument is push-button controlled and basic measurement data are entered manually. BearingChecker measures shock pulses, either with a built-in probe (BC200) or with an external transducer.

The LR/HR method was developed from the original Shock Pulse Method for condition diagnosis of rolling element bearings. It allows a precision analysis of oil film condition in the rolling interface and contains calculation models for finding the optimal lubricant. Poor lubrication is the root cause of most bearing failures.

The Shock Pulse Method is the monitoring and analyzation "True" operating condition of the bearing being monitored. Regardless of whether the bearing is 

SPM Instrument was formed in 1970 to develop and market the Shock Pulse Method of condition monitoring developed by Elvind Søhoel, the inventor 

In this paper, the accuracy of the remaining useful life estimation using extracted features from vibration signals and that from the shock pulse method are
