Lever arm slides forward for extra reach as it pivots into clamping position. Rugged design provides high force with excellent protection against flood coolant, chips, and welding spatter. Relatively small base area. Choose arm with swivel pad or long arm with radius nose. Lever 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.

Available in three clamp sizes, each with a choice of swivel pad or radius nose, double acting only. Clamping force at 7250 psi with swivel pad:
            4500 Lbs
            7200 Lbs
          11000 Lbs

 

Clamping Action 

Applying fluid pressure to the A (clamping) port advances the piston, which causes the clamping arm to slide forward in its side slots as it pivots. Switching pressure to the B (unclamping) port positively retracts the piston and the attached clamping arm.

 

Design Considerations 

The clamping lever must complete its full sliding pivot motion and starts its downward clamping stroke before contacting the workpiece. In conditions with excessive chips, the sliding slots may need to be cleaned occasionally.

 

Mounting & Fluid Supply

Two mounting options: 1) for low mounting, install cylindrical base in a bored hole, then fasten housing to base plate with two socket-head cap screws; 2) for high mounting, fasten optional intermediate plate to base plate with two socket-head cap screws, then fasten clamp to intermediate plate with two socket-head cap screws. Tighten cap screws to recommended torque in table.

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 CLR-9210-132-F Connecting Inserts (also install two CLR-810-F Port Plugs in the 1/4″ BSPP ports). Do not use NPT fittings.
Optional Position Sensoring 
All units are ready to install position sensing. Proximity switches can be installed in either the right or left side. Order two CLR-3829-164-PM inductive proximity switches, and two CLR-3829-099-PM right-angle plugs with cable. For pneumatic position sensing, order two CLR-3612-020-PM pneumatic jets.
