Roemheld Hinge Clamps for Low-Pressure Hydraulic Systems
1000 psi maxDouble Acting
This unique series of Hinge Clamps provides considerable clamping force at lower hydraulic pressures, allowing direct connection to the low-pressure hydraulic system of a machine tool. These are extremely compact, heavy-duty clamps with 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. Durable, economical clamp with an easy-to-clean mechanism, standard metallic wiper, and built-in throttle valve. The top-flange design is ideal for space-saving manifold mounting.
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.
Mounting & Fuid Supply
Dual mounting capability allows any clamp to be mounted using standard fittings or manifold mounting. Two 1/4" BSPP ports. For optional manifold mounting, use the O-ring ports underneath, instead of the standard ports. Do not use NPT fittings. For manifold mounting, the mounting surface must be ground flat to ensure proper O-ring sealing. Fasten clamp with four socket-head cap screws.
