Product Information

ROEMHELD Standard Swing Clamps – Threaded Cartridge, B1.892 (3, 5, 7 Series)

3000 to 7250 psi max

Single and Double Acting

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 threaded-cartridge version shown here is designed specifically for space-saving manifold mounting.

Available in three clamp sizes, single or double acting, with a choice of clockwise, counterclockwise, or zero° swing. Available with 45° and 60° swing angles by special order. Clamping force at 7250 psi for single-acting clamps with a pivoting clamping arm:

1060 Lbs (3 series)

2700 Lbs (5 series)

7300 Lbs (7 series)

Data Sheet

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 maximum fluid flow rate in 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.

Fluid passages must be drilled exactly as shown in the drawings. Do not use NPT fittings.

Clamping Arm

Standard Clamping Arm

3000 psi max

Gooseneck Clamping Arm

5000 psi max

Pivoting Clamping Arm

7250 psi max

Order clamping arm separately. 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.
