Pneumatic Mechanical Grips

Description

Pneumatic wedge action grips feature an open front design, which facilitates easy loading of large specimens. This series can accommodate round specimens up to 60 mm (2.36 in) in diameter and flat specimens up to 70 mm (2.75 in) thick. The compact design of these pneumatic wedge grips provides optimum use of the test area when installed on Instron’s floor model testing systems.


Specially suited for industrial environments where dust and metal chips may be present, these grips have protective dust covers that fit easily over the faces to shield the moving surfaces. Optional piggyback adapter plate furnishes an efficient method for mounting secondary load strings for lower capacity testing without removing the larger grip.


On the 2716-110 and 2716-120 Grips, the vee faces used for round specimens by design have a reduced area at the center, which compromises their ability to absorb high energy breaks without fracture. This grip uses a split-vee face configuration which allows the break energy to be dissipated without damaging the faces. On the W-5180 and W-5190 Grips, the considerable increase in size allows the use of a one-piece design grip face.

Principle of Operation

These grips are operated with a control knob mounted on the grip or with an Instron standard pneumatic control kit. Powered by pneumatic control, the faces are moved by a pneumatic piston - which eliminates a costly hydraulic pump and its control. When under load the wedge action provides additional clamping pressure to minimize specimen slippage.
