Page 1108 | 3.2 Mounting, Positioning, Leveling with Screws, Clamping and Supporting Elements With the aid of stainless steel 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 d 4 , which gua- rantees a parallel or right-angled arrangement. The pressure spring is placed between the toothed disks during assem- bly and ensures that the toothed disks separate properly when loosening. The scope of delivery includes two serrated locking plates, one pressure spring and, depending on the version, a threaded bushing. see also... • Serrated Locking Plates GN 187.4 (Sintered Steel / Stainless Steel) → Page 1100 • Serrated Locking Plates GN 189 (Plastic) → Page 1107 Information 1 d 1 2 z 3 Type 4 Material How to order 1 2 3 4 GN188-75-24-C-NI 3 Type A With pass-through hole, without bushing B With threaded bushing C With threaded bushing and centring step • Stainless steel precision casting NI AISI CF-8 • Threaded bushing Stainless steel AISI 304 • Pressure spring Stainless steel AISI 301 • Stainless Steel Characteristics → Page 2158 • RoHS Specification 4 1 2 d 1 z Number of teeth d 2 Type A d 3 Type B Type C d 4 d 5 −0,15 h 1 h 2 m s t w min.
