Bearing Structure
High precision journal bearing with two thrust faces. Ball locked cone. Hardfaced head bearing surface. Cone bearing inlaid with friction reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved, and suitable for high rotary speed.
Cutting Structure
Reinforcing the comprehensive mechanical properties of cutting tooth by using high quality tungsten carbide inserts of new formula and new techniques of insert bit.
Gauge Structure
The multiple heel position with gauge trimmer on the heel, tungsten carbide and hardfacing on the shirttail, strengthened spear point will enhance the gauge protection.

HR Series Rubber Sealed Bearing Bits
Journal bearing.Hardfaced head bearing surface.inner hole of cone is silver-plated.The load capacity and seizure resistance of the bearing is greatly improved.0 ring seal is made of the more wear resistance high saturated buna-N with the increased seal section and precisely designed sealing flflange in the cone sealing area increased the reliability of the seal.
HC Series Composite Sealed Bearing Bits
The series bits are sealed with composite rubber of sliding bearing,which can bear higher bit pressure and higher rotation speed,the service life of the bearings can be prolonged.
The bearing composite rubber seal ring, more suitable for the working environment and operating parameters of tricone bits.
The bit is made of cemented carbide inserts with high strength and wear resistance ,the inserts strength and wear resistance improved.
HM Series Metal Sealed Bearing Bits
Metal sealed with journal bearing. Hardfaced head bearing surface,inner hole of cone is silver-plated. The load capacity and sei-zure resistance of the bearing is greatly improved. High wear re-sistance and excellent cutting ability of the insert bit are given full play by using carbide compact of high strength and high toughness in combination with optimized compact numbers and rows,the exposure height and special shaped compacts
Mining Tricone Drill Bits
HENGJI BIT ,mining tricone drill bit is mainly used in large open-pit mining operations,such as open-pit coal mines,copper Mines,iron ore mines,molybdenum mines and other non-ferrous metal mined.The bits are used on rotary drills, with a proven reputation of high performance and low cost.
Mining tricone dril bit consists of a bearing structure,cutting structure,shirttal and lug enhancement structures,flow channel system and a thread connection.
The bearing structure consists of lug bearing,cone bearing,seal beaing,main rollers,minor rollers ,locking bearing balls,axle thruse plate, and recess thrust plate,they are categorised into air
