Three jaw protected parallel grippers OPH
   
The OPH self-centering parallel grippers can clamp the workpiece externally or internally. The cylindrical jaws shape and the apply of double edge scaper packing allow the application of this gripper in special environments. The OPH self-centering grippers have been designed to offer the following advantages :
 
° The body is in UNI39NiCrMo3 aluminum with hard anodized.

° Jaws and drive hub in UNI39NiCrMo3 steel with nitriding treatment.

° Inclined plane drive mechanism and cylindrical jaws with anti-rotation packing.

The OPH grippers have standard the following advantages :

° Open/closed control position housing with magnet on the piston.

° Axial air inled on base.

° Pneumatic (dry) or hydraulic operation.

Optional in the OPH grippers :

° External proximity control of the gripper jaw through the use of cylindrical or threaded proximity sensors with brackets and locating pins.

° Safety device with spring incorporated in the drive piston to maintain position without pressure.
