Spherical articulated lockable arm with magnetic base
The articulated arm with lockable spherical plain bearings and magnetic base is useful for orientating different devices, among which the digital microscope, the mechanical comparator or any other device that is 8 mm in diameter.
This device is an element of high mechanical precision, the two knurled knobs, loosen the spherical joints, allow a soft friction and therefore a millimetric positioning. Once tightened, the generated structure remains solidly robust.
Furthermore, its magnetic base, which can be activated by turning a special lever, allows the positioning and fixing of the arm on any ferrous metal surface.
