Principle of Operation
Pneumatic action grips clamp the specimen through a dual lever arm, actuated by an air cylinder built into the grip body. Gripping force can be controlled by adjusting the input air pressure and remains constant even if the specimen contracts in the gripped area providing the ultimate in 'follow-up' action. Pneumatic grips can be operated by a foot switch or by grip mounted air-valves (most models) making them quicker and simpler to operate than screw-action grips.
Application Range
- Type of loading: tensile, static, tension-tension cyclic tests - not suitable for high cycle fatigue tests
- Specimen material: plastics, metals, textiles, paper, thin sheet, foil, wire, film, and monofilaments
- Specimen shapes: round (wires) and flat specimen with or without shoulder tab ends

Easily Change Grips and Jaw Faces Without Any Tools
Unique Lock Nut Design
Designed for easy and comfortable hand-tightening to eliminate backlash. The smaller thread pitch also makes it easier to apply the required pre-load.
Quick Release Air Hose
A rotatable connection allows for tidy hose runs. Quick-connect makes disconnecting air supply quick and simple.
Quick Change Jaw Faces
Changes jaw faces in seconds without any tools or pins, and without removing the grips from the testing system.
Alignment Device
The optional specimen alignment device increases repeatability by helping operators load the specimen in the center of the grips.
Wire Alignment
The notch in the jaw face shields makes testing wires quicker and easier.
Self-Centering Design
Easily maintain axiality of loading without adjusting for changes in specimen thickness.
Offsettable Jaw Faces
Available on the 5 kN and 10 kN grips, offsettable jaw faces allow testing of irregular specimens or components (e.g. lap shear).
Specimen Holding Device
The optional specimen holding device allows the operator to close the grips with their fingers out of the test space.
Wide Range of Jaw Faces
Available in rubber-coated, serrated, smooth-ground, brake-lining (HFC), line-contact, wave-profile, and vee-serrated.
