Hereby, contrary to a clamping operation via a thread, these levers permit a torque-free clamping. The lever has been designed to ensure that its movement cannot exceed the max. clamping force. There are no loose components since they are all assembled and mounted in their correct order. With these clamping levers with eccentrical cam GN 927.4 / GN 927.5, clamping forces of up to 8 kN can be reached. The type A has the following benefits: The distance between the lever cam and the clamping surface is adjustable via a fine pitch thread, allowing the clamping position to be set easily with maximum clamping force. Also, the position of the lever relative to the clamping axis can be determined. see also... • Constructional Features → Page 663 Information Specification 5 • GN 927.4 Lever - - Zinc die casting - - Powder coated (abrasion proof epoxy resin) Black, RAL 9005 B Orange, RAL 2004 O Red, RAL 3000 R Silver, RAL 9006 S • GN 927.5 Lever Stainless steel (precision casting) AISI CF-8 This information applies to both standards: • Axis, lag nut / screw Setting nut / screw (only type A) Stainless steel AISI 303 • Contact plates Plastic, glass fiber reinforced - - Type A: Polyacetal (POM) - - Type B: Polyamide (PA) • Plastic Characteristics → Page 2158 • Stainless Steel Characteristics → Page 2166 • RoHS 1 2 2 3 l 1 d 1 d 2 l 2 In clamping position b d 3 d 4 d 5 h Stroke at 90° lever movement l 3 In clamping position l 4 Adjustable range l 5 In clamping position t Useable thread length  44 M  4 M  4 12 16 20 25 30 - - 12 12 15 14 0,5 13,2 2 2,2  8  44 M  5 M  5 12 16 20 25 30 35 40 12 12 15 14 0,5 13,2 2 2,2  8  63 M  5 M  5 16 20 25 30 35 40 50 16 16 19 18,5 0,75 16,3 2,5 3   10  63 M  6 M  6 16 20 25 30 35 40 50 16 16 19 18,5 0,75 16,3 2,5 3   10  82 M  6 M  6 20 25 30 35 40 50 60 20 20 25 22,5 1    19,5 3   3,7 12  82 M  8 M  8 20 25 30 35 40 50 60 20 20 25 22,5 1    19,5 3   3,7 12 101 M  8 M  8 20 25 30 35 40 50 60 25 26 30 27  1,5  25,3 4   4,8 15 101 M 10 M 10 20 25 30 35 40 50 60 25 26 30 27  1,5  25,3 4   4,8 15
