Roemheld Flat Clamps
7250 psi maxDouble Acting
Pivoting arm rotates completely back for loading clearance. Great new design provides excellent protection against flood coolant, chips, and welding spatter. Compact, flat design with choice of swivel pad or solid radius nose. Pivoting arm is designed to resist side forces at the clamping point. Dual mounting capability: all clamps are ready for standard fittings and manifold mounting. All units are ready for optional position sensing.
Clamping Action
Applying fluid pressure to the A (clamping) port advances the piston, which in turn advances the clamping arm via a connecting rod. Switching pressure to the B (unclamping) port positively retracts the piston and the attached clamping arm.
Design Considerations
Although these clamps have a large clamping range, the ideal clamping height in most cases is H3, because arm motion is totally vertical at that height. This avoids applying any horizontal force to the workpiece during clamping. Clamping force at height H1 is approximately 10% greater.
Mounting & Fluid Supply
Fasten using four socket-head cap screws. Two 1/4" BSPP ports, A for clamping, B for unclamping. For optional manifold mounting, use the A and B manifold ports underneath the clamp by unscrewing the sealing plugs and installing two Connecting Inserts. Do not use NPT fittings.
Optional Position Monitoring
All units are ready to accept position monitoring. Proximity switches can be installed in either the right or left side.
