GN 875 Swing clamps in block version and GN 876 Swing clamps with screw-in thread are used when the clamping point for inserting and removing the workpiece must be freely accessible on top.
During the clamping action, the arm is first swiveled by 90° and lowered, followed by the linear tensioning motion. The workpiece clamping must take place within the clamping stroke.
The angle orientation of the tensioning arm can be set arbitrarily during mounting on the swing clamp. When tightening the screw, the piston rod must not experience any torque. The clamping arm must therefore be held to prevent twisting.
The swing clamps in block version are equipped with a magnet ring piston and are therefore pre-fitted for end stop detection via sensor.
