Hydro-Mechanic guarantees a high clamping safety The piston assembly (pulling or pushing version) is subjected alternatively to the cup spring force or hydraulic pressure. This means that the cup spring packet is compressed more with increasing pressure. The hydraulic pressure is required only for the release stroke of the elements whereby the pull stud/pressure piece is released. This system ensures a high factor of safety since the clamping force generated is independent from the oil pressure and from pressure loss due to leakage. The full clamping force remains constant at all times. The short operating cycle times of the hydraulic power pack additionally save on costs and make it more economical. The spring clamping cylinders of the series ZSF and ZDF are robust and reliable elements which can be used in all applications where moveable machine parts (eg. fixtures, dies etc.) need to be clamped or locked into position.                                                           They are also used in workpiece and tool                                                           clamping operations.
