ROEMHELD Standard Swing Clamps – Top Flange, Cartridge Type, B1.8803 (3, 5, 6, 7 Series)

3000 to 7250 psi max

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 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)

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 to the A (clamping) port swings arm 90° over workpiece then clamps down. Switching pressure to the B (unclamping) port positively lifts arm then swings it back 90° for loading/unloading.

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.

An optional metallic wiper is available separately. This additional wiper protects the Viton wiper against physical damage, e.g. by hot chips. These Swing Clamps are ready for mounting the metallic wiper, which consists of a radially floating wiping disk and a retaining disk which is pressed onto the existing collar.

Mounting & Fluid Supply

Fasten clamp with four socket-head cap screws. 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.

Two different methods can be used to provide fluid connection. Method 1 requires drilling two small passages directly to the fluid holes in the clamp, at the correct orientation. If this is not possible, Method 2 requires additional machining to provide two radial grooves to feed fluid to the holes. 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.

Material

Piston > Alloy steel, nitrated for wear and corrosion resistance. Housing > Mild steel, nitrated for wear and corrosion resistance. Piston rod wiper > Viton.
