“SC” Series NEW PRODUCT BULLETIN Swing Clamp Cylinders featuring. . . • Magnetic Piston • Clamp arm with adjusting bolt • Four rod end flats for clamp arm positioning all included as standard at no extra charge! Specifications The clamp arm rotates 90° as it extends away from the workpiece providing clearance and access for unload/load operations. Double acting operation and standard magnetic piston offer positive cycles, durability and workpiece detection features. Extruded aluminum body mounts directly and rigidly to equipment surfaces in a minimum of space. Operation cycle: 1) Clamp arm extends (straight line) as it releases clamp load from workpiece. 2) Arm rotates 90° to full extend position. 3) When retracting, clamp arm swings 90°: Model Code R = clockwise direction, Model Code L = counterclockwise rotation. 4) With clamp arm in position over the workpiece, it follows a straight line path to apply clamping force.
