The SAFE 20 is the newest generation of clamping cylinders with a patented collet lock. This provides a form-fit connection between cylinder, plug, and workpiece and improved vibration damping. SAFE 20 is easy to maintain and less susceptible to dirt than previous clamping cylinders. Pull in force is 12,500 N / 2,800 Ibs per cylinder and retention force is 40,000 N / 9,000 Ibs per cylinder.
