– High-strength and wear-resistant carbide teeth are used, and the number of tooth rows, number of teeth, height of exposed teeth and tooth shape are optimized to improve the efficiency and life of the cutting structure of the drill bit.
– With new journal bearing structure which greatly prolongs the service life of the bearing, and has the ability to withstand high drilling pressure and adapt to high rotational speed.
– The performance of the new fluorinated composite sealing ring is improved, and it is more suitable for the working environment and use parameters of the roller cone bit.
– The oil storage system can balance the pressure difference inside and outside the bearing, and provide good lubrication guarantee for the bearing system.
– X feature, the main cutting teeth of the cone are wedge-shaped teeth, which have the characteristics of high cutting efficiency and strong anti-breaking ability for specific medium-soft to medium-hard formations, effectively improving the drilling speed of the drill bit and prolonging the service life of the drill bit.
– T feature, there is a trimming row between the gauge row and bevel row to protect the cones and trim the well wall.
