This roller bearing swivel is designed to isolate equipment's rotational torque from the pipe or cable being pulled through an underground boring. Several adapters are available to attach this swivel to various Roto-Bore tooling. The current selection of adapters include a weld-on stud for attachment to a backreemer and snap-in adapters for each of our drill rods. This quality pullback swivel uses a roller thrust bearing assembly to handle thrust loads up to 4000 lbs. For even greater anti-friction, anti-wear performance the swivel also contains two additional bronze bearings and a recess protected greese fitting for flushing after each use.
