YNJQ-300 hydraulic bucking machine has five hydraulic sycliders, in working, the pipe is fixed , the five hydraulic cylinders synchronized able to clamp the coupling and rotate continuousely. Every cy
YNJQ 300 bucking unit is a machine designed for disassembly and assembly through 360° continuous rotation and is provided with high precision torque automated test system. This machine is mainly used for disassembly and assembly of some cylinder threaded connection parts such as casing collar, tubing collar, oil well pump collar, tool joint, packer adapter, downhole tool and drilling tools in oil field. In addition, it is also feasible to additionally install eccentric adjustment unit, disassemble and assemble eccentric workpiece(100mm).
