Page 796 | 2.4 Tensioning with Clamping Mechanisms GN 861 Toggle Clamps Pneumatic, Heavy Duty 1 Size 2 Type 3 Coding How to order 1 2 3 GN861-1000-EP-M 2 Type EP Solid clamping arm 3 Coding M Magnetic piston Toggle clamps GN 861 have been constructed in such a way as to make them easy to unmount. The bearing pins are axially fixed with circlips. This allows the clamping arm to be modified to suit any particular application. To ensure an extended life of the mechanical parts as well as the air cylinders, the operating pressure should not exceed 6 bar and a com- pressed air maintenance unit should be installed upstream. Toggle clamps GN 861 are available as version M (magnetic piston). In conjunction with a GN 896.3 proximity switch the piston position is sensed and the generated signal can be used in sequence control systems. see also... • More Information to Toggle Clamps (Pneumatic) → Page 790 Information • Base Cast steel Black lacquered • Other parts Steel St 60 Zinc plated, blue passivated • Bearing pins Case hardened • Double-action air cylinder with adjustable cushioning Max. pressure 6 bar • All moving parts Lubricated with special grease • RoHS Specification • Proximity Switch GN 896.3 → Page 808 Accessory Size h 3 l 1 ≈ l 2 ≈ l 3 ≈ m 1 m 2 m 3 m 4 r ≈ s 1000 25 410  90 155 65 12,5 65 48 140 13 2000 35 487 113 176 70 15   70 56 172 13 1 Size F H in N Holding capacity F S in N Clamping force at 6 bar ≈ b 1 b 2 b 3 d 1 d 2 Compressed air connections Inside Ø Connection tube h 1 ≈ h 2 1000 10000 2500 102  90 20 10,5 G 1 ⁄ 4  8 145 80 2000 20000 3600 112 100 20 10,5 G 3 ⁄ 8 10 171,5 90
