– Adopting the Journal bearing structure, it has the ability to withstand medium WOB and adapt to higher ROP.
– The O-ring seal is made of wear-resistant and high-temperature-resistant fluorinated high-saturated nitrile rubber, which effectively improves the reliability of the bearing seal and thus increases the service life of the drill 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.
