Product Information

7250 psi max

Double Acting

As push clamps, these double-acting cylinders are useful in automated systems where the return stroke must be completed within a certain time. They are also very useful as pull clamps. Manifold mounting allows an extremely compact, space-saving design. These versatile cylinders provide considerable force in a small size, and can be placed very close together.

Available in five body diameters with metric threads. The smallest four alternatively available with inch threads. Push force at 7250 psi:

2250 lbs

3500 lbs

5500 lbs

9000 lbs

14000 lbs

Data Sheet

Clamping Action

Applying fluid pressure to the A (clamping) passage advances the plunger. Switching pressure to the B (unclamping) passage positively retracts the plunger. Passages can also be reversed to use as a pull clamp.

Mounting & Fluid Supply

Screw clamp into fixture up to the top flange, and tighten to the recommended seating torque. Alternatively, the top flange can be recessed in a counterbored hole, for flush mounting. Threaded-cartridge clamps have O-ring seals on their outside diameter, so they require a precision mounting hole. Carefully follow hole-preparation instructions in the drawings. The overall depth of the bored hole must be strictly observed, because the bottom acts as a stop (to make the short length of this unit possible). The insertion chamfer and the entrances of the fluid passages into the bored hole must be rounded to avoid damaging the seals during clamp installation. Fluid passages must be drilled exactly as shown in the drawings. Do not use NPT fittings.

Optional Viton Seals

For high-temperature applications (212° to 300° F), we offer Viton seals in all sizes. Please contact factory for more information.
