7 7/8'' 200mm IADC 637 Hard Rock Drilling Conical Roller Chisels Tricone Bit

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
