They can be assembled safely and easily with a high clamping force by reducing the slot height, without damaging the surface of shafts and ax- les. As compared to semi-split shaft collars, split shaft collars can even be assembled radially. The thread d 3 for sizes d 1 = 30 to 36 is designed as a through hole; for sizes d 1 = 42 and larger, it is designed as blind hole. see also... • Semi-Split Stainless Steel Shaft Collars GN 7062.3 (with Damping Washer) → Page 1151 • Split Shaft Collars GN 707.2 → Page 1154 Information 1 2 d 1 d 2 H10 Recommended shaft tolerance h11 b 1 b 2 d 3 s x ≈ Max. protrusion of cap screw Adjustable hand lever for d 3 30 B 12 - 11 13 M 4 2,1 0,7 GN 311-30-M4-12-SW 32 B 14 - 11 13 M 4 2,1 0,7 GN 311-30-M4-12-SW 36 B 15 B 16 13 15 M 5 2,1 1,4 GN 311-30-M5-13-SW 42 B 18 B 20 15 18 M 5 3   0,6 GN 311-30-M5-15-SW 48 B 22 B 25 15 18 M 5 3   0   GN 311-45-M5-16-SW 55 B 28 B 30 15 18 M 6 3   0,5 GN 311-45-M6-18-SW 60 B 32 B 35 15 18 M 6 4   0,4 GN 311-45-M6-19-SW 65 B 40 - 15 18 M 6 4   0,5 GN 311-45-M6-20-SW • Stainless steel NI Sintered steel AISI 316LHC • Damping washer Elastomer (PUR) - - 70 Shore A - - Temperature resistant up to 80 °C - - Transparent • Socket cap screw DIN 912 Stainless steel AISI 304 • ISO Fundamental Tolerances → Page 2151 • Elastomer Characteristics → Page 2158 • Stainless Steel Characteristics → Page 2166 • RoHS Specification 3 • Adjustable Hand Levers GN 311 → Page 1159 Accessory GN 7072.3 Split Stainless Steel Shaft Collars with Damping Washer
