Pulling swivels are a nessary and important part of Horizontal Directional Drilling.
The swivel has to be able to stand up to not only the tensile forces caused by the pullback, but also the rotational forces and the side loads caused by rocks or certain other conditions.
For this reason the bearings in our swivels are suitable for absorbing both thrust and radial loads. Our swivels have specially designed seals to prevent ingress of dirt to the bearings which would cause premature failures. The seals can withstand mud, grime and anything else found underground and are designed to be easily serviceable.
