These indexing plungers are universally applicable due to their prevention of misalignments and positioning errors of the mating indexing bores. The type C / CK with rest position are used for such applications where the plunger has to stay in its retracted position. During assembly, the max. tightening torques shown in the table should not be exceeded when securing the lock nut. see also... • List of Indexing Plunger Types → Page 884 ff. • Distance Bushings GN 609.5 (to Limit the Thread Length) → Page 952 Information • Threaded body - - Steel zinc plated, blue passivated ST - - Stainless steel AISI 303 NI • Plunger pin Stainless steel AISI 303 • Pressure spring Stainless steel AISI 301 • Knob plastic (Polyamide PA) - - Black, matte finish - - Not removable • Load Rating Information → Page 2132 • Plastic Characteristics → Page 2158 • Stainless Steel Characteristics → Page 2166 • RoHS Specification 4 3 Type B Without rest position (knob), without lock nut BK Without rest position (knob), with lock nut C With rest position (knob), without lock nut CK With rest position (knob), with lock nut 1 2 d 1 Pin -0,05 Bore +0,03 +0,08 d 2 d 4 e l 1 l 2 l 3 l 4 l 5 min. l 6 l 7 A/F max. tighte- ning torque in Nm Spring load in N ≈ Initial End  3 M  6       12 6,9 30 3,5 12 4,5 10 32,5 7 6 2 3 12  3 M  6 x 0,75 12 6,9 30 3,5 12 4,5 10 32,5 7 6 3 3 12  4 M  6       12 6,9 30,5 4  12 4,5 10   33   7   6 2 3 12  4 M  8 x 1   16 9,2 39,5 4,5 16 6 13,5 43 9,5 8 8 5 24  5 M  8       16 9,2 40   5  16 6   13,5 43,5 9,5 8 7   5 24  5 M 8 x 1   16 9,2 40   5  16 6   13,5 43,5 9,5 8 7   5 24  5 M 10 x 1   18 11,5 42,5 5  16 6   13,5 46   9,5 10 22 5 24  6 M 10       18 11,5 49   6  20 7,5 17   52  10,5 10 15   5 21  6 M 12 x 1,5 21 13,8 52   6  20 7,5 16,5 55  10,5 12 38 5 21  8 M 12       21 13,8 59   8  24 9   20,5 63,5 13,5 12 20   6 22  8 M 12 x 1,5      21 13,8 59   8  24 9   20,5 63,5 13,5 12 20   6 22  8 M 16 x 1,5 25 19,6 63,5 8  24 9   20,5 68  13,5 17 80 6 22 10 M 16 x 1,5 25 19,6 67,5 10   26 9   22,5 72,5 14   17 80 4 27
