    Swing Clamps – Threaded Cartridge (2 Series)

    Power Workholding 

    Swing Clamps utilize a sturdy helical-cam mechanism to swing the clamping arm clear for unrestricted loading. The threaded-cartridge Swing Clamps shown here provide considerable clamping force in a small size, because they can operate at a full 7250 psi with any standard clamping arm. These Swing Clamps incorporate our unique safety-clutch mechanism. If the clamping arm strikes an unexpected object during its swing, the clutch disengages to avoid damaging the object or the clamp's helical-cam mechanism. Clamping arm can be mounted to start its 90° swing from any position within 360°. Threaded-cartridge Swing Clamps are designed specifically for space-saving manifold mounting.

    Available in one clamp size, single acting and double acting (see Related Products below), with a choice of clockwise, counterclockwise, or zero° swing. Available with 45° and 60° swing angles by special order.

    Application Information

    Manifold mounting allows placing these swing clamps very close together.

    When clamping over a work support, these swing clamps are ideally matched with small threaded-body work supports (1500 lbs load capacity at 7500 psi). The design rule in such applications is that work-support load capacity should be at least 2X clamping force.

    This fixture has three workpieces held by nine swing clamps with short clamping arms. Short arms extend only .16" onto the workpiece but are ideal for some small parts.

    Clamping Action

    Available with clockwise, counterclockwise, or zero° swing

    Swing Clamps are pull-type cylinders where part of the total stroke is used to swing the piston, and the remaining stroke is available as the clamping range. Applying fluid pressure swings arm 90° over workpiece then clamps down. Single-acting version has a fast, totally dependable spring return that lifts arm then swings it back 90° for loading/unloading. Optional fluid return (double acting).

    Design Considerations

    These Swing Clamps incorporate our unique safety-clutch mechanism. If the clamping arm strikes an unexpected object during its swing, the clutch disengages to avoid damaging the object or the clamp's helical-cam mechanism. Do not exceed the maximum fluid flow rate in the table. For extended clamp life and proper operation of the safety clutch, a simple flow-control valve may be required if the fixture is powered by a high-flow-rate power source and only contains a few clamps. Clamping time should be at least one second.

    Mounting & Fluid Supply

    Screw clamp into fixture up to the body hex. Threaded-cartridge clamps have O-ring seals on their outside diameter, so they require a precision mounting hole. Carefully follow hole-preparation instructions in the drawings. Round the sharp edge on the upper fluid passage with a 3/16" dia ball as shown in Detail Z of the drawings (otherwise the lower O-ring can be damaged when the clamp is screwed in). Check for burrs with a finger before installing. Fluid passages must be drilled exactly as shown in the drawings. Do not use NPT fittings.

    Clamping Arm

    Order clamping arm separately. Standard Clamping Arms can be used at pressures up to 7250 psi on these clamps.
