Air-Powered Hold-Down Toggle Clamps
Use for repetitive clamping and in production environments. Air from one inlet port engages the clamp, and air from the other inlet port disengages it. Clamps maintain the full-rated holding capacity even with a loss of air pressure. Fittings (not included) are required to connect the clamp's ports to a control valve and an air line.
Clamps with open arm allow you to move the holding screw to any position along the arm. To achieve maximum holding capacity, position the screw closest to the base. Capacity decreases by as much as 65% when the screw is positioned at the end of the arm.

Long-Life Dual-Mount Air-Powered Hold-Down Toggle Clamps
These clamps have double the service life of other air-powered toggle clamps. Use for repetitive clamping and in production environments. They have two sets of holes for mounting on the bottom or side. Air from one inlet port engages the clamp, and air from the other inlet port disengages it. Clamps maintain the full-rated holding capacity even with a loss of air pressure. Capacity decreases by as much as 65% when mounting at the end of the arm. Fittings (not included) are required to connect the clamp’s ports to a control valve and an air line.

Air-Powered Hold-Down Fixture Clamps
Adjust the air pressure to quickly and consistently clamp and release parts. The arm on these clamps rotates 90° into position over the workpiece and then moves straight down to clamp. Disengage to rotate the arm out of the way and load or unload parts. Also known as swing clamps, they are used with a solid state switch or Reed function switch with M8 male 3-pin connectors. Connect the clamp's ports to a control valve and an air line. Clamps mount with screws.
Clamps with rubber-tipped holding screw are nonmarring. Tip is removable.

Threaded Air-Powered Hold-Down Fixture Clamps
Screw these clamps directly into a tapped hole and use air pressure to quickly and consistently clamp and release parts. The arm rotates 90° into position over the workpiece and then moves straight down to clamp. Disengage to rotate the arm out of the way and load or unload parts. Also known as swing clamps, they're used with a solid state switch or Reed function switch with M8 male 3-pin connectors. Connect the clamp's ports to a control valve and an air line. To hold clamps in an untapped hole, use a mounting block (sold separately).

Air-Powered Push Toggle Clamps
Use for repetitive clamping and in production environments. These clamps secure when the plunger is fully extended to hold a workpiece from the side. Air from one inlet port engages the clamp, and air from the other inlet port disengages it. Clamps maintain the full-rated holding capacity even with a loss of air pressure. They have a threaded plunger to accommodate threaded holding screws and other threaded fixtures (not included). Fittings (not included) are required to connect the clamp's ports to a control valve and an air line.

Vacuum Workholding Plates
Also known as vacuum chucks, these plates secure thin and flexible parts that can’t be held with vises or clamps for milling, drilling, routing, and finishing operations. Connect the system to your shop’s compressed air supply and it's ready to use. For applications requiring only part of the plate surface, use the gasket cord to seal off the area.

Air-Powered Locating Pin Retractors
A good choice for automated clamping, these retractors use compressed air to extend and retract a locating pin, protecting the pin from damage in applications where fixtures move through a process, such as along a conveyor belt. Commonly used in automated welding applications, the highly accurate air cylinder ensures repeatable locating. Each retractor has two air inlet ports, one extends the pin and the other retracts.
Retractors have a position sensor with an M12 connection for activating relays and controllers in automated processes.
Secure a locating pin to the top of the retractor using four M5 set screws (not included). For easy alignment, shoulder-style locating pins are recommended.

Short-Stroke Clamping Air Cylinders
Also known as air clamps, these cylinders are used to apply force in holding applications. All are single acting with air-extend actuation—also known as push style, air extends the rod and cylinders have a spring that returns the rod to its original position.
For technical drawings and 3-D models, click on a part number.
Rotary Clamping Air Cylinders
Clamp items in place to complete a step in your manufacturing process. These air cylinders rotate while actuating, so you can position, assemble, and inspect items. The body of these air cylinders has threaded through-holes on the face and sides, so you can mount them directly to equipment and thread accessories on. The rod is internally threaded, allowing you to attach an arm as needed for your application.
The piston is magnetic, so you can use these slides with sensors (not included) to activate relays and controllers. When the piston moves past a sensor, the sensor activates. You can use multiple sensors—one for each action you want to trigger.
