Indexing plungers with a rest position are used for such applications where the plunger has to stay in its retracted position. In that case, the knob is retracted and afterwards turned by 90°. A notch keeps the plun- ger in this position. see also... • List of Indexing Plunger Types → Page 884 ff. • Indexing Plungers GN 717 / GN 817 (Steel / Stainless Steel) → Page 912 / 913 / 898 • Indexing Plungers GN 617 / GN 617.1 (Steel / Stainless Steel) → Page 892 / 893 Information 3 Type C With plastic knob, without lock nut CK With plastic knob, with lock nut CN With stainless steel knob, without lock nut CKN With stainless steel knob, with lock nut • Stainless steel AISI 316 A4 Plunger pin, chemically nickel plated • Knob - - Plastic (Type C / CK) Polyamide (PA) Black, matte finish - - Stainless steel AISI 316 (Type CN / CKN) Not removable • Pressure spring Stainless steel AISI 316Ti • Load Rating Information → Page 2132 • ISO Fundamental Tolerances → Page 2151 • Plastic Characteristics → Page 2158 • Stainless Steel Characteristics → Page 2166 • RoHS Specification 4 1 d 1 2 l 1 3 Type 4 Material How to order 1 2 3 4 GN818-5-5-CK-A4 1 2 d 1 Pin  −0,02 −0,05 Bore H7 l 1 d 2 d 3 d 4 k 1 k 2 l 2 l 3 l 4 l 5 A/F Spring load in N ≈ Initial End  4  4 M  8 x 1 16 16 14 20 35 16 5 41 10 3,5 11  4  6 M  8 x 1 16 16 14 22 35 16 5 43 10 3 11  5  5 M 10 x 1 19 18 16 24 40 18 6 48 12 3 12  5  8 M 10 x 1 19 18 16 27 40 18 6 51 12 3 14  6  6 M 12 x 1,5 23 22 20 29 48 22 6 57 14 4,5 16  6  9 M 12 x 1,5 23 22 20 32 48 22 6 60 14 4 20  8  8 M 16 x 1,5 28 27 24 35 58 26 8 69 17 6 23  8 12 M 16 x 1,5 28 27 24 39 58 26 8 73 17 7 26 10 12 M 16 x 1,5 28 27 24 41 58 26 8 75 17 7,5 32 12 15 M 20 x 1,5 33 32 28,5 46,5 71,5 33 10 89,5 22 9 32 GN 818 Stainless Steel Indexing Plungers AISI 316, with Rest Position
