Page 257 | 1.3 Adjusting with Handwheels and Cranks GN 520.1 Disk Handwheels Plastic, Bushing Steel Disk handwheels GN 520.1 are renowned in particular for the matte pas- sivated aluminum ring in the front. The tough, reinforced black plastic (Duroplast PF) and high gloss polis- hed surface give the disk handwheels a touch of elegance. The ergonomic handle is easy to grasp and makes the disc handwheels easier to use. This standard replaces the previous handwheels GN 520. see also... • Countersunk Washers GN 184 (for Axial Fixing) → Page 1090 • Disk Handwheels GN 520.2 (Plastic, Bushing Stainless Steel) → Page 258 • Disk Handwheels GN 521 (Plastic, Threaded Bushing Steel) → Page 254 Information • Plastic Duroplast (Phenolic PF) - - Reinforced - - Temperature resistant up to 110 °C • Hub bushing Steel, blackened • Threaded bushing Brass • Handle GN 598 Plastic, Duroplast Spindle steel, zinc plated • Keyway P9 DIN 6885 Page 1 → Page 2078 • ISO Fundamental Tolerances → Page 2151 • Cross Holes GN 110 → Page 2080 • Plastic Characteristics → Page 2158 • RoHS Specification 1 d 1 2 Bore code 3 d 2 4 Type How to order 1 2 3 4 GN 520.1-125-K14-D • Without hub bore On request 2 Bore code B Without keyway K With keyway * only available in Type D 1 3 d 1 d 2 H7 Bore d 3 d 4 d 5 d 6 d 7 b l 1 l 2 l 3 l 4 r Ø Handle Type A Type D Type A Type D Type A Type D Type A Type D Type A Type D Type A Type D  50 10 - 16 16  16  - -  25 25 26 12 12 9 19 19  22 22 28 19  14  63 10 - 20 20  20  - -  31 31 28 13 13 10 24 24  28 28 40 24  18  80 10 12 20 18  18  28 28 43 43 30 14 14 10 28 28  31 31 40 32  18 100 10 12 24 22  20  35 35 54 54 39 15 21 12 36 33,5 40 46 50 39  21 125 12 14 32 26,5 26,5 44 44 70 70 46 15 28 15 38 38  44 57 65 50  23 140 14 - 32 26,5 26,5 44 44 70 70 48 19 28 15 38 38  46 55 65 58  23 150 14 16 32 26,5 26,5 44 50 70 80 48 18 30 15 38 38  49 61 65 62  23 175 16 18 40 33  33  55 55 90 90 56 19 32 15 43 43  54 66 80 72,5 26 200 18 20 40 33  33  55 55 90 90 60 21 32 15 43 43  58 68 90 82  28 225 * 20 22 49 - 40  - 66 - 110 66 - 33 15 - 44,5 - 71 90 94  28 250 22 24 * 49 40  40  66 66 110 110 70 25 36 15 44 44,5 65 76 90 106  28 300 26 - 58 58  58  94 94 148 148 82 25 36 18 56 56  75 87 90 132  28 4 Type A Without handle D With revolving handle Original design VDN.FP -A
