They can be assembled safely and easily with a high clamping force by reducing the slot height, without damaging the surface of shafts and axles. 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 7062.2 (with Flange Holes) → Page 1150 • Semi-Split Shaft Collars GN 706.2 → Page 1148 Information 1 2 d 1 d 2 H10 Recommended shaft tolerance h11 b ±0,2 d 3 d 4 d 5 d 6 m s x ≈ Max. protrusion of cap screw Adjustable hand lever for d 3 Bore series 1 Bore series 2 Bore series 1 Bore series 2 30 B 12 - 11 M 4 4,5 3,5 M 4 21 - 2,1 0,7 GN 311-30-M4-12-SW 32 B 14 - 11 M 4 4,5 3,5 M 4 23 - 2,1 0,7 GN 311-30-M4-12-SW 36 B 15 B 16 13 M 5 5,5 4,5 M 5 25,5 26 2,1 1,4 GN 311-30-M5-13-SW 42 B 18 B 20 15 M 5 5,5 4,5 M 5 30 31 3 0,6 GN 311-30-M5-15-SW 48 B 22 B 25 15 M 5 6,5 5,5 M 6 35 36,5 3 0 GN 311-45-M5-16-SW 55 B 28 B 30 15 M 6 6,5 5,5 M 6 41,5 42,5 3 0,5 GN 311-45-M6-18-SW 60 B 32 B 35 15 M 6 6,5 5,5 M 6 46 47,5 4 0,4 GN 311-45-M6-19-SW 65 B 40 - 15 M 6 6,5 5,5 M 6 52,5 - 4 0,5 GN 311-45-M6-20-SW • Stainless steel NI Sintered steel AISI 316LHC • Socket cap screw DIN 912 Stainless steel AISI 304 • ISO Fundamental Tolerances → Page 2151 • Stainless Steel Characteristics → Page 2166 • RoHS Specification 3 • Adjustable Hand Levers GN 311 → Page 1159 • Damping Washer GN 7072.30 → Page 1161 Accessory GN 7072.2 Split Stainless Steel Shaft Collars with Flange Holes
