Swivels
The 1-J and 2-J swivels from King Oil Tools are engineered for drilling household water wells, drilling shot holes in marshes and jungles and for use on light hydraulic rigs and small jetting rigs. The bearings are duplex, angular-contact type, mounted back-to-back. They are sealed in the housings, and provision is made for lubricating by means of a grease gun. The housing parts are made of nickel-iron for water well rigs and of aluminum alloy castings for seismograph rigs. The packing units consist of two molded composition rubber rings, and a hardened wear ring is interposed between the rubber rings. King Oil Tools
