improved, and it is more suitable for the working environment and
use parameters of the roller cone bit.
- The new sealing structure matches the bearing, thus greatly
improving the service life of the drill bit.
- T feature, a protection carbide inserts row is added between the
outer rows and cone back rows for the purpose of cone protection
and well wall dressing.
