Product description

Information

Swivel ball joints GN 784 allow precise and stepless adjustment of the ball pivot within the swiveling 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 forces on the ball. This force is easily applied with the adjustable lever (Identification no.1). When adjusting, the clamping must be completely released.

The ball joint can be mounted from below with the d₅ 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 torques increases the stop torque, but may result in increased wear of the clamping mechanism.
