Shock pulse monitoring

SPM is an abbreviation for the Shock Pulse Method, which is a patented technique for using signals from rolling element bearings as the basis for efficient condition monitoring of machines. Instant evaluation of bearing condition is given in an easily understood green-yellow-red color scheme.

The Shock Pulse Method, originally invented in 1969, has been further developed and broadened and is now a worldwide accepted philosophy for condition monitoring of rolling bearings and machine maintenance.

SPM HD – High Definition Shock Pulse Method

High Definition shock pulse monitoring in a very broad RPM range, including ultra low-speed applications (0.1 - 20 000 RPM range).

Shock Pulse Method dBm/dBc

For over fifty years, the original Shock Pulse Method (SPM) has been very successfully used to obtain a fast, easy, and reliable diagnosis of the operating condition of rolling element bearings.

Shock Pulse Method LR/HR

The LR/HR method allows the precision analysis of oil film condition in the interface between the outer and inner races and contains calculation models for finding the optimal lubricant.
