Product Information

ROEMHELD Hinge Clamps – Top Flange, Cartridge Type, B1.8251

3600 psi max

Double Acting

Hinge Clamps have a sturdy linkage configuration that moves the clamping arm forward as it pivots into clamping position. This specially designed linkage allows the clamp to exert nearly perfectly vertical clamping force. The clamping arm retracts fully for clear loading from above. Ideal for clamping in narrow recesses. Durable, economical clamp with an easy-to-clean mechanism and standard metallic wiper. The top-flange cartridge-type version shown here is designed specifically for space-saving manifold mounting.

Available in four clamp sizes, double acting only, each with either a standard clamping arm with swivel contact bolt, a long clamping arm for customization, or without a clamping arm for a user-manufactured arm. Clamping force at 3600 psi with standard clamping arm:

850 Lbs

2200 Lbs

3200 Lbs

4800 Lbs

Clamping Action

Applying fluid pressure to the A (clamping) port advances the piston, which is connected to the clamping arm. The arm moves forward as it pivots into position via a linkage. Switching pressure to the B (unclamping) port positively retracts the piston and the attached clamping arm.

Design Considerations

The ideal clamping height in most cases is "H", because arm motion is totally vertical at that height. This avoids applying any horizontal force to the workpiece during clamping.

Mounting & Fluid Supply

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 in the drawings. Do not use NPT fittings.

Optional Position Sensing

These clamps can be ordered with an extended piston rod for inductive or pneumatic position monitoring. For inductive position monitoring, order an inductive monitoring end cap (separately or already installed), two CLR-3829-198-PM inductive proximity switches, and two CLR-3829-099-PM right-angle push plugs with cable. For pneumatic position monitoring, order a pneumatic monitoring end cap (separately or already installed). Monitoring devices can be turned to any of the four sides.
