Area of application
The ball joint holders are available in various ball diameters, which have different holding forces. A small lever pressure is sufficient for stepless locking with high holding force. The base can be selected for clamping, for screwing on firmly, or with screwed-in high-performance magnets.
A quick-release clamp for optimally aligning cameras, monitors, sensors, or measuring devices. Carving plates, carving balls, or various clamping and holding tools are used in woodworking. A wide variety of clamping and holding devices are screwed on in instrument making and model making. Suitable adapters and extensions of all kinds can be screwed on via the thread on the ball. Optimal support for repairing e-scooters, e-bikes, and bicycles in a free-floating position. Universities, research centers, and laboratories have appreciated the versatile application and usage possibilities for years.
The clamp-on attachment is suitable for workbenches with a maximum tabletop thickness of up to 80 mm. The screw-on attachment can be connected to workbenches, tables, and base plates via the four 9 mm through holes. The high-performance magnets offer individual attachment, which can also be changed quickly.

Maximum torque: Ball Ø 40 mm approx. 24 Nm, Ball Ø 60 mm approx. 100 Nm
Holding forces of the ball at the height of the threaded pin: Ball Ø 40 mm approx. 45 kg (441 N), ball Ø 60 mm approx. 140 kg (1,372 N). Degreasing the ball increases the clamping force.
Clamping foot: Table top thickness max. 80 mm
Chrome-plated, rustproof steel parts
The adjustment screw on the lower seat of the ball allows the ball’s movement to be adjusted from loose to very tight.
Please note that we cannot guarantee the holding forces of safety-relevant parts without knowing your specific application. The ball may behave differently under different physical conditions than in our test laboratory under optimal test conditions.
