There have been a number of developments in bearing technology used in tricone bits :

The bearing assemblies of the first roller cone bits were open to the drilling fluid.

Sealed bearing bits were introduced in the late 1950s, to extend the bearing life of insert bits.

The sealing mechanism prevents abrasive solids in the mud from entering and causing excess frictional resistance in the bearings.

The bearings are lubricated by grease which is fed in from a reservoir as required.

Some manufacturers claim a 25% increase in bearing life by using this arrangement .

Hebei Crossing Drill Bit Manufacture CO.,LTD is a professional supplier of drilling tools,including tricone bit,PDC tricone bit,Hole opener,single cone bit and so on.With years of study and refining of the introduced technology, we have succeeded in the field of product research with proprietary intellectual property rights.Also, we have made major breakthrough in the lines of analogue simulation in bottom-hole flow field,profile optimization,design of inserts arrangement and low torque,material and manufacturing techniques etc. As a result, our products own better characters of service and ranges of application.Mainly used for oil and gas,mining,geothermal,construction and so on.

Milled tooth tricone bits

1, Soft formations ( IADC 114 - 117 )
These bits are designed to drill the softest formations such as soft shales,red beds, and clays, with high durability and maximum penetration rates.

2, Soft to medium formations( IADC 121,124,126,134,136,137 )
These bits are designed to drill formations such as shales, medium soft limestone, Medium sandstone and other formations with intermittent hard streaks.

3, Medium to medium hard formations ( IADC 213,214,215,217)
These bits are designed to drill formations such as hard sandstone, dolomite, and broken formations with hard cherty streaks

4. Hard formations(IADC 317, 337)
These bits are designed to drill formations such as hard limestone, dolomite, hard sandstone and chert, etc.
