Performance characteristics of roller cone bit

1. High-strength and high-toughness cemented carbide teeth are used to improve the impact resistance of the teeth and reduce the rate of broken teeth;

2. Optimized design of the number of rows of teeth, the number of teeth, the height of the exposed teeth and the unique shape of the alloy teeth give full play to the cutting ability and cutting speed of the drill;

3. The circlip is used to lock the cone, which can withstand high drilling pressure;

4. The inner hole of the cone is welded with anti-friction alloy to improve the anti-occlusion ability of the bearing;

5. Highly saturated nitrile rubber O-ring is used, and the optimized sealing compression improves the reliability of the bearing seal;

6. The all-rubber oil storage bag that can limit the pressure difference and prevent the drilling fluid from entering the lubrication system provides good lubrication for the bearing system and ensures the normal operation of the "O"-shaped sealing ring, which improves the working life of the drill bit;

7. The use of a new type of lubricating grease that can withstand 250°C high temperature and low wear improves the high temperature resistance of the sealing and lubrication system of the drill bit.
