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).
Clamps with rubber-tipped holding screw are nonmarring. Tip is removable.

Use the power of hydraulic fluid to quickly, consistently, and repeatedly clamp and release parts with a greater clamping force than air-powered hold-down fixture clamps. All of these clamps have a threaded body so you can screw them directly into a tapped hole in a fixture. Connect the clamp's ports to a hydraulic control valve and a hydraulic fluid line. To use these clamps, you’ll need a short or long clamp arm (sold separately), or add your own custom clamp arm.
Single-acting clamps use hydraulic fluid to hold material while an automatic spring return releases the material. Clamped material will automatically be released if they lose hydraulic power.
Double-acting clamps use hydraulic fluid to hold as well as release material. They’re more reliable and consistent for high-production applications than single-acting clamps.
Clamps with 90° rotation let clamp arms move into position over your material and then move straight down to clamp. Once the clamp is released, they rotate the clamp arm out of the way so you can remove the material.
Attach clamp arms to the piston on your clamp to hold down material. Short clamp arms have a threaded hole, so you can use a holding screw for a more secure installation. Long clamp arms offer the extra length you need to reach material that is farther away from your clamp. They will, however, reduce the holding capacity of the clamp.
