Product Features

 Hejian New Field Petroleum Machinery Co., Ltd

TCI Bit/Roller Roller Bit/Cone Drill Bit/water/oil well drilling,sealed metal bearing

1)Main Features

1.Cutting Structure

The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.

 

2.Gauge Structure

Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.

 

3.Bearing Structure

High precision bearing with two thrust faces. Balls lock the cone.Hardface heard bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved and suitable for high rotary speed.

 

4.Seal and Lubrication

The advanced metal seal package consists of two metal seats and two elastic energizers. Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force, and achieve the bearing seal. In the drilling, metal seal are relatively dynamic, and the energizers are static. This will improve the reliability and durability of bearing seal. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
