CZJ320W Hydraulic Bucking Unit is specifically designed to cater to the structures and mechanical features of completion tools. It offers the most precise and efficient means of achieving proper make-up/break-out torque either on or off the rig floor for completion tools, drilling tools, oil recovery tools, geological tools and other thin-walled tubes. One of the main advantages of CzJ-320W is the design whereby the clamping force is proportional to the torque provided. Moderate clamp force, small make-up torque and its clamp diameter range makes it suitable for make-up and break-out of completion tools.
