Page 804 | 2.4 Tensioning with Clamping Mechanisms GN 863 Toggle Clamps Pneumatic, Heavy Duty Type 1 Size 2 Type 3 Coding How to order 1 2 3 GN863-1000-EPV-M 2 Type EPV Solid clamping arm 3 Coding M Magnetic piston Toggle clamps GN 863 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 once it is dismantled, 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 863 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 sys- tems. see also... • More Information to Toggle Clamps (Pneumatic) → Page 790 Information • Body 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 2 h 3 l 1 ≈ l 2 ≈ m 1 m 2 m 3 m 4 r s 1000 132,5 25 217,5 80 50 12,5 50 - 144 13 2000 161 35 246,5 100 54 12,5 58 45 168,5 14 1 Size F H in N Holding capacity F S in N Clamping force at 6 bar ≈ b 1 ≈ b 2 b 3 b 4 d 1 d 2 Compressed air connections Inside Ø Connection tube h 1 ≈ 1000 10000 3250 102  90 80 20 10,5 G 1 ⁄ 4  8 355 2000 20000 5600 112 100 90 20 12,5   G 3 ⁄ 8 10 425
