Swing Clamps utilize a sturdy helical-cam mechanism to swing the clamping arm clear for unrestricted loading. The Standard Swing Clamps shown here accept a wide variety of clamping arms, with maximum allowable operating pressure depending on the type of arm selected (3000 to 7250 psi max). 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°. The top-flange cartridge type shown here is designed specifically for space-saving manifold mounting.
Available in four clamp sizes, double-acting only, with a choice of clockwise, counterclockwise, or zero° swing. Available with 45° and 60° swing angles by special order. Also available with a longer clamping stroke (25mm) by special order. Clamping force at 7250 psi with a pivoting clamping arm:
          1100 Lbs     (3 series)
          2800 Lbs     (5 series)
          4500 Lbs     (6 series)
          7800 Lbs     (7 series)
Design Consideration
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.

Clamping Action 

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). Available with clockwise, counterclockwise, or zero° swing.

Mounting & Fluid Supply 

Two mounting methods: 1) Mount through a tapped hole in the fixture plate, securing with a lock ring; 2) Mount through a bored hole in the fixture plate, securing with two lock rings.  1/4″ BSPP port (two for double-acting clamps) for use with standard fittings. Do not use NPT fittings.

Clamping Arm 
Order clamping arm separately  – see clamping arm accessories. Maximum allowable operating pressure depends on the type of arm selected. Choose a Standard Clamping Arm for 3000 psi max, a Gooseneck Clamping Arm for 5000 psi max, or Pivoting Clamping Arm for 7250 psi max (requires a rear support). Longer, custom clamping arms will further reduce allowable operating pressure, inversely proportional to arm length.

Swing Clamps are ported from below so that all tubing lines run underneath the fixture plate. Clamps are installed in threaded collars, which are bolted to the plate with cap screws. The collars allow simple, economical fixture building and easy height adjustment.
