GN709.3 Clamping Pad, Adjustable, Steel
These clamping pads GN 709.3 are used as mobile supports or as spring plungers for clamping workpieces. They can also be used as a back stop.
After the clamping process, the contact surfaces of clamping pads type BR and RR automatically reset themselves to their initial position. This prevents the bearing from jamming in an inclined position when the workpiece is inserted.
The bearing can be rotated by a maximum of 9° and is secured against further rotation.
