Product Information

ROEMHELD Compact Clamps – Top Flange, Cartridge Type, B1.827

3600 psi max

Double Acting

Compact Clamps have a sturdy lever mechanism that pivots into clamping position. These clamps are extremely compact both in footprint and overall height. The clamping lever pivots a full 90° for clear loading even when using custom long clamping levers. Ideal for clamping in narrow recesses. The top-flange cartridge-type version shown here is designed specifically for space-saving manifold mounting. Integrated pneumatic clamping monitoring allows checking for workpiece presence and clamping pressure.

Available in four clamp sizes, double acting only. Clamping force at 3600 psi with standard clamping arm:

560 lbs

900 lbs

1680 lbs

2360 lbs

Compact Clamp

Clamping Action

Applying fluid pressure to the A (clamping) port advances the piston, which pivots the clamping arm into position. Switching pressure to the B (unclamping) port positively retracts the piston and the attached clamping arm.

Mounting & Fluid Supply

Version 1

With Bottom Cover

for Open-Bore Mounting

Manifold mounting in a bored throughhole, or with accessory mounting block using standard fittings.

Version 2

Without Bottom Cover

for Closed-Bore Mounting

Manifold mounting in a closed pockethole

Fasten clamp with four socket-head cap screws. 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. Fluid passages must be drilled exactly as shown. Do not use NPT fittings.

Clamping Arm

Choice of standard short clamping arm (Left) or long blank clamping arm for customization (Right).
