100 kN Universal Hydraulic Wedge Action Grips The Instron® 100 kN hydraulic wedge action grips may be used in static or dynamic materials testing applications. The interchangeable grip jaw faces accommodate both flat or round specimens. The grip design maintains a constant gripping force on the test specimen, regardless of the applied test forces. This controlled gripping force is applied by the grips as long as there is adequate hydraulic pressure supply that is active and connected. Features and Benefits • Rated capacity: ±100 kN (22 kip) • Side-entry design with full access for easy specimen insertion • Interchangeable jaw faces suitable for gripping various material types • Suitable for a wide range of specimen thickness without the need to change jaw faces • Jaw faces for flat and round specimen geometries • Optional adjustable specimen stops on flat faces provide repeatable and accurate specimen centering • Suitable for tension, compression, and fatigue testing up to the full reverse-stress dynamic rating • Operated from a load frame mounted hydraulic grip manifold or via a stand-alone grip controller • Temperature range: +4 to +65 °C (+39 to +149 °F) Principle of Operation Although an external hydraulic supply provides pressure to open and close the grips, each grip functions independently of the other. When gripping pressure is applied, the relative vertical position of the specimen/jaw faces remains unchanged, which prevents specimen load generation during the gripping process. Application Range • Type of loading: Static or dynamic, reverse stress • Specimen material: Metals, plastics, composites • Specimen geometries: Round section (not buttonhead) or flat specimens with or without shoulder tab Products for Materials Testing Once the grip faces contact the specimen, the hydraulic pressure produces a vertical force on the grip head. The grip force will remain constant as the design automatically compensates for sp
