    Description
    Hollow-piston cylinders 3.2130, single acting

    Manual positioning of the element on the die clamping edge.
    Clamping by the application of hydraulic pressure to the piston and unclamping by spring force. 
    By means of the T-bolt the die is clamped against the clamping surface of the press ram or bed.

    Applications

    • on press beds and rams
    • on machines and equipments for clamping and locking
    • when the available space is limited
    • at environmental temperature up to 120° C


    Special features

    • optimum adaptation to the clamping surface by spherical disk
    • T-bolt, secured against loosening
    • ideal force transmission
    • convenient and compact design with gripping surface
    • clamping force from 60 kN up to 104 kN
    • large clamping stroke
    • no interfering edges when inserting the dies
    • easy retrofit
    • piston hardened and ground
    • easy installation
    • fully resilient stroke limitation

     

    Versions

    Hollow-piston cylinders     with spherical disk for the adaptation to the clamping surface with adjusted and secured T-bolt (alternatively: without or with attached T-bolt)

    Hollow-piston cylinders 3.2130 - Versions

    Version with a total stroke of 20 mm
    Optimum adaptation to varying heights of the clamping edges of dies by an increased total stroke of 20 mm (higher total stroke on request).
    Technical design, clamping forces and dimensions are as indicated on data sheet 3.2130 for the standard design.

    Version with variable clamping dimension
    Freely adjustable and flexible adaptation to suit varying heights of clamping edges of the dies by quick and easy adjustment of the tie rod by means of a lock nut. The tie rod is inserted through the hollow-piston cylinder and adjusted to the the correct dimension by means of the lock nut.
    In this version, the cylinder has a through hole instead of a thread. Technical design, clamping forces and dimensions are as shown on catalogue sheet 3.2130 for the standard design.
