A roller-cone bit is a drill bit used for drilling through rock, for example when drilling for oil and gas.. Characteristics. Drilling bits are attachments that are added to the end of a drillstring to perform the cutting necessary to penetrate the many rock layers between Earth's surface and oil/gas reservoirs.

Products Tapered Roller Bearings. Tapered Roller Bearing. Tapered roller bearings (TRBs) utilize rolling elements that are shaped like a truncated cone (Figure 1), and are constructed so that all tapered surfaces converge at a common apex point on the bearing centerline to yield true rolling motion (Figure 2).

The sealed-bearing Roller Cones Drill Bits system package uses a reservoir and pressure compensation system, as shown in Fig.2, to protect its seal's integrity. The compensation system balances internal oil and seal pressure with external mud hydrostatic pressure toffective lubricating action than the heavy grease, hence the extended bearing life.

Roller-cone bits are generally classified as either tungsten carbide insert (TCI) bits or milled-tooth bits. To assist in comparison of similar products from various manufacturers, the International Association of Drilling Contractors (IADC) has established a unified bit classification system for the naming of drill bits.

Rollercones produce more sized product on the first pass than any competitive cone. Roller bearing tolerances are ten times less than on bronze-bushing shaft cones. The roller bearings ensure a true setting. Eighty percent of the force through the wedge plate is directed to crushing because roller bearings run more efficiently.

Tricone bit bearings are what make the cones on a Tricone spin. There are four common types of bearings - standard open roller bearings, air-cooled roller bearings, sealed roller bearings, and sealed journal (friction) bearings. We'll look into these different types of bearings, and try to explain the differences.

Roller cone bits are of two types: milled-tooth and insert. They are designed to drill rocks of various types and strengths. The milled-tooth bits are generally used when tooth wear is not a critical issue, whereas the insert bits with tungsten carbide inserts are used when tooth wear becomes the limiting factor in the life of the bit.
