Series GRM4 clamps

The GRM4 pneumatic workholding clamps are designed for heavy-duty industrial applications where high clamping force and reliability are essential. These clamps generate a total clamping force up to 2,224 N, making them ideal for robotics, transfer systems, and press applications. The design offers multiple jaw styles, including standard, shovel, flange, and toolable jaws, for a wide range of applications. The clamps lock in the closed position, ensuring workpiece retention in case of pressure loss. Options include switches for position and double-sheet detection, as well as various jaw tips for specific material thicknesses and surfaces.

Advantages
