Carr Lane CLR-1887-244 | 7 Series 15.00mm Clamping Stroke x 7300 lbs Clamping Force Standard Swing Clamp

Product Information

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 Degree swing from any position within 360 Degree. The flange-base version shown here provides many plumbing options, including manifold mounting. Available in four clamp sizes, single or double acting, standard fittings or manifold mounted, with a choice of clockwise, counterclockwise, or zero Degree swing. Available with 45 Degree and 60 Degree swing angles by special order. Double-acting clamps are also available with longer clamping strokes (25mm or 50mm) 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)          4200 Lbs     (6 series)          7300 Lbs     (7 series)

Application Information

Flange-base swing clamps are used together with Work Supports on a pallet fixture. All components are manifold mounted, so the fixture is entirely free of tubing lines.

Clamping Action

Available with clockwise, counterclockwise, or zero Degree 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 Degree over the workpiece then clamps down. Single-acting version has a fast, totally dependable spring return that lifts arm then swings it back 90 Degree 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

Version 1Standard Fittings Version 2Manifold Mounting These Swing Clamps are available in two versions, one for use with standard fittings and one for manifold mounting. Version 1, for standard fittings, has a 1/4" BSPP port (two for double-acting clamps). Version 2, for manifold mounting has O-ring ports underneath instead of standard ports. Do not use NPT fittings. For manifold mounting, the mounting surface must be ground flat to ensure proper O-ring sealing. Both clamp versions can be fastened to the top of a fixture plate with four socket-head cap screws inserted through the flanged base from above. Version 2 clamps, with standard fittings, can alternatively be mounted: a) Through a bored hole in the fixture plate, fastening with four socket-head cap screws inserted through the flanged base from below;b) Through a tapped hole in the fixture plate, securing with a lock ring;c) Through a bored hole in the fixture plate, securing with one or two lock rings.

Standard Clamping Arm3000 psi max Gooseneck Clamping Arm5000 psi max Pivoting Clamping Arm7250 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.
