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

Design of journal bearings

 

Journal bearings must provide a balanced bearing geometry and adequate journal strength and must maximize the thickness of the high-pressure lubricating film developed during hydrodynamic lubrication. The thickness of lubricating films is affected by:

- Surface areas
- Journal and cone diameters
- Clearances between journal and cone

 

Manufacturing tolerances must be precise so that surfaces run true. Roundness of journal and cone surfaces is important, and if any part of a bearing is out of round, the effectiveness of the lubrication regime will be adversely affected.

 

The metallurgy of a bearing must be balanced to minimize heat generation during boundary lubrication. Cone-bearing surfaces are steel. Soft, silver-plated sleeves are installed on the journal. Silver polishes easily, and minor surface irregularities from machining are quickly smoothed. This smoothness ensures low-friction operation and uniform lubricant flow over the bearing surface
