Pneumatic wedge action grips feature an open front design, which facilitates easy loading of large specimens. This series can accommodate round specimens up to 3.4” (19mm) thick. The compact design of these pneumatic wedge grips provides optimum use of the test area when installed in testing machines.
Principle of Operation
These grips are operated with a control knob mounted on the grip or with a 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.
