Locking disc with centring bush

With the aid of serrated locking plates GN 188, standard components can be interlocked and firmly attached in defined angular increments. They are joined by welding. The toothing is positioned exactly on the alignment holes d4, which guarantees a parallel or right-angled arrangement. The tooth count of 24 / 36 enables the adjustment in 15° or 10° steps, resulting in the indexing positions listed in the separate table. The thrust spring is installed between the serrated locking plates and ensures that the serrated locking plates separate properly when removed. The scope of delivery includes two serrated locking plates, one thrust spring and, depending on the version, a threaded bushing.
