• • Product Information

  • 1. The floating bearing structure is adopted. The floating element is made of new materials with high height, high elasticity, high temperature resistance and high wear resistance. The surface is treated with solid lubricant. While reducing the relative linear speed of the bearing pair, reducing the temperature rise of the friction surface can effectively improve the bearing life and reliability under the conditions of high WOB or high speed drilling technology. 　　

    2、 Adopt high-precision metal seal. The metal seal uses a pair of carefully designed and processed metal seal rings as the axial dynamic seal of the bearing, and two highly elastic rubber energy supply rings are respectively located in the sealing area of the tooth palm and the tooth wheel as the static seal. The optimized seal compression amount ensures that the sealing surfaces of the two metal rings always keep in good contact. 　 　

3. The steel ball locks the cone and adapts to high speed. 　　

4. The full rubber oil reservoir, which can limit the differential pressure and prevent drilling fluid from entering the lubrication system, provides a good lubrication guarantee for the bearing system. 　　

5. New grease resistant to 250 ° C high temperature and abrasion is used. 　　

6. The insert bit adopts high degree and high toughness cemented carbide teeth. The number of tooth rows, tooth numbers, exposed tooth height and unique alloy tooth shape are optimized to give full play to the high wear resistance and good cutting ability of the insert bit. A new type of wear-resistant material is welded on the tooth surface of the steel tooth drill bit, which not only maintains the high penetration rate of the steel tooth drill bit, but also improves the service life of the cutting teeth of the drill bit.
