NJ360-35 premium thread  tubing/ casing coupling bucking unit is the special equipment applied to the processing of premium thread oil pipe. It is also applied to the coupling screw of the premium thread such as FOX, RTR,NK3SB,VAM,BGT as well as the common thread .
With slight mark and the depth of being less than 0.05mm, the floating arm tong is able to inspect the make-up torque precisely and display the torque of inflection point clearly during the make-up process. It changes speed automatically during the make-up process and the low rotation speed is lower than  5r/min. It is thus applied to the processing demand of premium threads.
