Hydraulic clamp 240-40

workpieceswingdouble-acting

Swing clamps, with block housing (F) Swing clamp cylinders release the clamping point on the workpiece. With this, it is easy to change the workpiece. This hydraulic swing clamp cylinder operates as double-acting traction cylinder, whereas part of the stroke is used to rotate the piston. The model with 0° swing angle operates only vertical as traction cylinder. To guarantee a long lifetime the cylinders have an integrated metal wiper as standard. For hydraulic oil supply, the cylinders are equipped with threaded port and manifold connection with O-ring for drilled channels. You can select between right or left turning models with various standardized swing angles. The integrated overload protection protects the swing mechanism from demage due blockage of the rotation or improper assembly of the clamping arm. For any risk of exceeding the permitted volume flow a throttle check valve must be interposed into the oil supply line. Counter-hold the clamping arm when tightening or loosening the counter nut in order to prevent torque transfer to the piston rod and to avoid damage to the ball guide. Models with 0°, 30°, 45°, 60° and 90° swing angles are available. The permitted operating pressure is depending from the clamping arm length. Models with other swing angles can be supplied as special designs. Except from standard clamping arms also special clamping arms can be assembled. The maximum operating pressure of 500 bar does not apply for each clamping arm length. For details about the permitted operating pressure see the diagrams on the data sheet.
