Electric Drives and Controls Hydralics Linear Motion and Assembly Technologies Pneumatics Service Clamping Device, Series 2709 Technical data
Pneumatic Open mechanism Technical Data Type Power transmission by means of toggle action Working pressure range 2 to 8 bar (29 to 6 psi) Ambient temperature range -0 C to +50 C (+4 F to +22 F) Opening angle 05 and 35 Pressure medium Compressed air ISO 8573-:200, class 6-4-3 or lower* Materials Clamp head Aluminum, black anodized Clamp arm Steel Toggle mechanism Steel Cylinder body Aluminum, black anodized Seals Nitrile rubber Application area Mainly for clamping, in conjunction with machining or spot welding. Non toggle locking clamping devices: The mechanism does not over-travel the 0-position when clamped. Toggle locking clamping devices: The mechanism over-travels the 0-position and holds its position even with a drop in pressure to the cylinder. This reduces the opening angle a few degrees. * Particle size 5 µm, dew point 3 C, oil content mg/m³ Technical Information (for furter information and calculation, see section 5) Piston Ø [mm] 20 32 50 63 Clamp torque at 6 bar(87 psi) (clamping pos.)[nm] 2 50 50 280 (in.lbs) (06) (443) (328) (2478) Clamp torque at 6 bar (87 psi) (open position)[nm],2 3,5 9 20 (in.lbs) (0.6) (3.0) (79.7) (77.0) Weight [kg] (lbs) 0,7 (.5),3 (2.9) 3, (6.8) 5,7 (2.6) Part No. non toggle locking Clamping device Symbol Piston dia. 20 32 50 63 Opening Arm Part no.
