1. Overview:

    The PWS-5 electronic servo fatigue testing machine is mainly used for the tension and compression fatigue life testing of various vehicle engine suspensions, chassis suspension assemblies, components, and structural parts. It can also be used for three One-point bending and four-point bending fatigue tests can also be used for dynamic performance and fatigue life tests of other structural parts and components.
