Roemheld CLR-1873-405-ASC | M30x1.5 Thread Air-Powered Swing Clamp

ROEMHELD Air-Powered Swing Clamps-All Threaded, J7.201

100 psi max (Air)
Double Acting

Air-operated version of the popular hydraulic Swing Clamps, for applications requiring light clamping force. Arm swings clear for easy loading, with a sturdy helical-cam mechanism. Arm can be mounted to start its 90° swing from any position within 360°. A standard magnetic piston allows monitoring of clamping and unclamping position.

Application Information

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 air 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

See Application Information for a typical air-connection example. Use an Air Check Valve between the air supply and the Air Clamping Valve to protect against pressure loss if the air supply fails. Always use a Filter/Regulator/Lubricator. For extended clamp life, install an Air Extractor Dryer before the Filter/Regulator/Lubricator. Swing motion must not be restricted in any way. Be sure to adjust the contact bolt so that the clamp completes its full swing stroke and starts its clamping stroke before contacting the workpiece. Do not use with hydraulic fluid.

Mounting

Three possible 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; 3) Mount in a Threaded Mounting Flange, securing with a Lock Ring, then fasten the Threaded Mounting Flange to the fixture with two socket-head cap screws (allows side mounting).

Mounting with Optional Flange Base

Several possible mounting methods: 1) fasten to top of fixture plate with four socket-head cap screws inserted through the flanged base from above; 2) Mount through a bored hole in the fixture plate, fastening with four socket-head cap screws inserted through the flanged base from below; 3) Mount through a tapped hole in the fixture plate, securing with a lock ring; 4) Mount through a bored hole in the fixture plate, securing with one or two lock rings.

Optional Position Sensing

All of these clamps have a magnetic piston as standard and are ready to accept position sensing. Proximity switches can be oriented at any angle. Sensors are mounted with hose clamps.
