1. Introduction
This series of rock bit adopts metal seal with journal bearing,
which can drill stably with high rotary speed. It’s the ideal part
of well section. The size range of rock bit is from 3-1/2 to 26
inch and IADC varies from 117 to 837.
2. Main Structure Features
a. Metal face seal journal bearing. New processes of head bearing
hardfacing and cone bearing silver plating are used to improve the
load capacity, anti-galling ability and stability of the bearing .
b. Varies shapes of inserts can be equipped on this series of bits,
including scoop inserts, wedge inserts, conical-spherical inserts
and double spherical inserts, etc. Drilling process & formation
and bit are efficient integrated by scientific insert shape
selection to realize safety and high efficient drilling.
c. For this series, a row of inserts is added between gage row and
heel row to trim borehole wall and protect cone shell.
