The GN 187.6 set allows the locking of the different combinations of toothed elements GN 187.5.
During assembly, the centring bushing is positioned in the hexagonal slot of the toothed element, while the screw or the threaded element will be inserted into the end of the opposite toothed element, allowing screwing until the desired locking.
The use of stainless steel thrust springs GN 187.2 allows the toothed clamping elements GN 187.5 to separate from each other when the pressure is released.
The type GN 187.6-K is generally used in applications that require frequent adjustment. The different components are delivered together in the set unassembled.
