    Description
    I 4.120 Fixture Clamp, concentric clamping

    Application
    The fixture clamps are used for machining of dimensionally stable workpieces in single or multiple clamping fixtures.
    Due to their compact design they can be arranged in a very limited space. Fixture clamps are especially suitable for series manufacturing 
    in automated mode.
    The double-acting cylinder function combined with central lubrication and good swarf protection guarantees a high process safety.

    Description
    The fixture clamp with concentric clamping function consists of a very slim basic body with 2 integrated hydraulic cylinders.
    The piston forces are transfered via a guided connecting link to the two clamping slides so that a centric synchronism is obtained. All threads and ports are at the bottom to allow a space-saving arrangement of several clamping points in a very limited space. If fixing from below is not possible an adaptor plate for manifold mounting or tube connection is available.
    As accessory also blanks of clamping  jaws are available for adaptation to the workpiece contour. 

    Important notes
    The fixture clamp is only suitable for exterior clamping. 
    Lubricate at the latest after 500 clamping cycles the clamping slide via the central lubrication. Never use the complete clamping stroke to guarantee safe clamping of the workpiece.

    Max. operating temperature 80 °C
