Technical Data

Type Power transmission by means of toggle actionWorking pressure range 2 to 8 bar (29 to 116 psi)Ambient temperature range -10 °C to +50 °C (+14 °F to +122 °F)Opening angle 105° and 135°Pressure medium Compressed air ISO 8573-1:2001, class 6-4-3 or lower*

Materials Clamp head Aluminum, black anodizedClamp arm SteelToggle mechanism SteelCylinder body Aluminum, black anodizedSeals Nitrile rubber

Application areaMainly 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.
