GN 784 mounting clamps with swivel ball joint allow precise and variable adjustment of the ball pivot within the rotation range. This is a particular advantage when adjusting scanners, cameras, lighting, monitors, etc.
Thanks to the efficient clamping mechanism, only small amounts of torque on the clamping screw result in comparatively strong clamping pressure on the ball. This force is easily applied by the clamping lever (Identification no.1).
The mounting clamp with swivel ball joint can be mounted from below with the d4 internal thread or together with the GN 784.1 flange, available as an accessory, using three through-holes from above.
For a permanent high stop torque, the contact surfaces of the balls must be kept free of grease. Exceeding the recommended tightening torque increases the securing of the mounting clamp with swivel ball joint in its end position, but may result in increased wear and potential failure of the clamping mechanism.
