    Description
    B 1.8921 Swing Clamps with Reinforced Swing Mechanism

    Hydraulic swing clamps are used for clamping of workpieces when it is essential to keep the clamping area free of straps and clamping components for unrestricted workpiece loading and unloading. Due to the sturdy swing mechanism and the extended switch rod they are particularly suited for:

    • Clamping fixtures with workpiece loading via handling systems
    • Transfer lines
    • Test systems for motors, gears, axes, etc.
    • Automatic manufacturing systems
    • Assembly lines

     

    This line is a further development of the proved ROEMHELD swing clamps with the aim to improve process safety in linked clamping systems.
    The most important data are as follows:

    1. Omission of  the overload protection device
    In the case of a slight collision with the clamping arm during loading and unloading of the fixture, the angular position of the clamping arm will be maintained.
    Less critical are the weight of the clamping arm or an increased swing speed.

    2. Reinforced swing mechanism  
    The reinforced swing mechanism endures a collision of the clamping arm with the workpiece during clamping up to a pressure of 100 bar.

    3. FKM wiper   
    This wiper has a high chemical resistance when using aggressive cutting fluids.

    4. Further types of bodies
