Connection thread M12 x 1.5 mm (special thread) suitable adapters are gladly requested directly 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 (441N), Ball-Ø 60 mm ca140 kg (1.372N). Degreasing the ball increases the clamping force. Connection base: Table thickness max. 80 mm Screw base: 4 x 9 mm through holes Magnetic base: Holding force 32 kg horizontal, 15 kg vertical (magnet without cap) ESD models: Discharge value 10^7 and 10^8 Ohm EPA suitable. For working in electrostatically protected areas (ESD workstation/ESD protection zone). The foot parts can be attached at the earthing point with a 10 mm push button. Aluminium castings powder-coated steel parts chrome-plated, stainless Please note for safety-relevant parts that we cannot give up any security of the holding forces without knowing your specific application. The sphere can behave differently under different physical conditions than in our test laboratory with an optimal test environment.
