Double Bearing for Horizontal Operation

This unit is equipped with a lower bearing that allows the driller to drill horizontally without wearing out the bottom packing.
Simplified design – one-piece outer housing to eliminate misalignment, extending the packing and stem life.

Descriptive Design:

The Mark V side inlet swivels were designed for mounting below the top head drive to prevent fluid contamination in the gear boxes.

All components used in the manufacture of the Mark V-SI side inlet swivel are of high-grade alloy steel with induction hardened wear areas to extend the life of the expansive stem. The main feature is a rigid mounting of the bearings, mounted in a one-piece housing, eliminating run-out, thus extending the packing and stem life. The strength of the unit is based on the size of the tool joint used on the stem as it is a one-piece design and of high-strength alloy steel.

This unit is equipped with a lower bearing that allows the driller to drill horizontally.
