Product Description
These journal bearingtricone bits are used to medium hard formation with highercompressive strength and thick & hard stringers, such as limestone,hard shale, mudstone and sandstone, ets.
1.Tungsten carbide insert tooth, sealed and gage protection journalbearing,hardfaced head bearing surface. Cone bearing inlaid withfriction reducing alloy and then silver plated. the load capacityand seizure resistance of the bearing is greatly improved
2.O-ring seal is made of the more wear resistance high saturatedbuna-N with the section and precissely designed sealing flange inthe cone sealing area increased the reliability of the seal.
3.The bit bearing is ball which can be applied to high rotary speeddrilling.
4.All rubber compensator is used which can provides the bearingsystem with good assurance of lubrication
5.New type of grease that can sustain high temperature up to 250Cis utilized.
6.High wear resistance and excellent cutting ability of the insertbit are given full play by using carbide compacts of high strengthand high touhness in combination with optimized comjpact numbersand rows, the exposure height and special shaped compacts.
7.Meet strictly of API and ISO standard
8.Manufacturer of TCI tricone bits, steel tooth tricone bits andPDC bits
9.High , reasonable price and best service.
10.Delivery on time
11.Good feedback of the clients
