FEATURES: Air-operated version of our 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. The all-threaded version shown here is ideal for mounting through a fixture plate, to keep air lines out of the working area. An optional flange base is available for additional mounting possibilities.
SIZES: Available in five sizes, each with a choice of clockwise or counterclockwise swing — see Dimensions page for part numbers. Clamping force at 100 psi with standard arm:| | 41 Lbs | | (3 Series) | | | 107 Lbs | | (4 Series) | | | 164 Lbs | | (5 Series) | | | 256 Lbs | | (6 Series) | | | 407 Lbs | | (7 Series) |
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.
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. Order two CLR-3829-119-PM inductive proximity switches, and two CLR-3829-099-PM right-angle plugs with cable (PNP connection). Sensors are mounted with hose clamps – see Dimensions page for part number.
DESIGN CONSIDERATIONS: See Air Connection Example on Applications page. Use an Air Check Valve between the air supply and the Air Clamping Valve to protect against pressure loss if the air supply fails. Alway 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.
CLAMPING ARM: Order clamping arm separately. Standard clamping arm has a maximum allowable operating pressure of 100 psi. Longer clamping arms will reduce allowable operating pressure, inversely proportional to arm length (see charts on Dimensions page).
CONSTRUCTION: Piston rod > stainless steel. Housing, guide bushing, piston, and flange > hardcoated aluminum. Clamping arm > Steel.
