SR - Compensation System

cilindri-rotanti
With the unique internal compensation system, these swing clamp cylinders maintain the clamping point with maximum precision over a long operating time.
They can be equipped with clamp arm position control valves to ensure precise workpiece clamping. Further accessories are the VRF flow control valve that controls the swing speed and the metal wiper designed to protect the main wiper.
Larger clamping areas provide either reduced dimensions and lower costs or higher clamping forces.
Rated for operating pressures of up to 500 bar.
