Good result of the FLRT natural diamond drill bit. Thank you.

We have ordered the tricone bits to drill shallow oil well and some times make hdd hole openers. The quality is good

Bearing systems

Roller cone bearing systems are designed to be in satisfactory operating condition when the cutting structure of the bit is worn out. To achieve this standard of bearing performance, modern goals for seal and bearing system life are 1 million or more revolutions of a bit without failure, as opposed to ≈300,000 or fewer in the recent past. To achieve this goal, research into bearing, seal, and lubricant designs and into materials that improve seal and bearing life is ongoing.

 

Roller-cone bits primarily use two types of bearings: roller bearings and journal bearings, sometimes called friction bearings. Each type is normally composed of a number of separate components, including:

1-Primary bearings
2-Secondary bearings
3-Seal system
4-Features that resist thrust loading
5-Cone retention balls
6-A lubrication system
