You are here:
1. Adopt high strength and high wear resistance carbide teeth, enhanced the intensity of the teeth and abrasion resistance.
2. Adopt new journal bearing structure, greatly extend the life of the bearing, has the ability to withstand high wob and adapt high rotation speed.
3. New fluorinated rubber sealing ring performance improvement, more suitable for the working environment and the operating parameters of rock bit.
4. New type sealing structure make sealing performance and bearing matching, thus greatly improve the service life of drill bit.
