ABSTRACT:
A harsh environment swivel is disclosed. The swivel is of the type having first and second swivel heads located at opposite ends of a generally hollow swivel body. A swivel shaft is attached to the first swivel head and secured within the hollow body by a locking nut. The swivel shaft rotates about tapered roller bearings which transmit tensile loading from the swivel shaft to the hollow body. A plurality of progressively more restrictive seals restrict the passage of debris into the interior of the hollow body. In a further embodiment, a swivel having independently rotating swivel heads at either end is disclosed. A method of flushing debris from the interior of a swivel is also disclosed.
