The shock pulse method was invented in the late 1960s. In rolling element bearings, there is a phenomenon where electric waves, or elastic waves, or shock pulses, or impact signals, are generated. The amplitude of these impacts is determined by three different parameters.

LEO232 SPM Spectrum (2). LEO233 ISO 10816 vibration monitoring with spectrum (1) Unlike vibration transducers, the shock pulse transducer.

Shock pulse amplitude is due to three basic factors: Rolling velocity (bearing size and rpm) Oil film thickness (separation between the metal surfaces in the rolling interface). The oil film depends on lubricant supply and also on alignment and pre-load. The mechanical state of the bearing surfaces (roughness, stress, damage, loose metal particle).
