Standard Swing Clamps – Top Flange, Cartridge

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)

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.

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.
