1.Metal sealed roller cone bit
Metal seal bearing adopts metal seal ring, bearing is sliding bearing characteristics, this reasonable design concept, so that the metal sealed of roller cone bit service life is longer, of course, all kinds of oil fields, for the field of high requirements for the bit can use such a roller cone bit, but the price of roller cone bit is expensive.
The bearing sealing system adopted in this series of drills has the characteristics of low linear velocity of bearing pair and low temperature rise of friction surface.The application of new synthetic grease improves the bearing's resistance to high temperature, wear and extreme pressure, and provides longer service life and higher reliability in vertical and directional Wells.
2.Rubber sealed roller cone bit
Rubber sealed roller cone bit is adopted, bearing is rubber sealed bearing characteristics, this kind of bit and metal sealed roller cone bit usage is the same, but the service life of the bit is relatively short, of course, it also has its advantages, roller cone bit price is cheaper ;
Rubber sealed rolling bearing bit is an ideal and economical tool for high speed drilling with low bit pressure.We can recommend a reasonable roller cone bit for your use according to the actual situation of the customer. Choosing the right roller cone bit/tricone bits can improve the drilling speed and service life.
