Bearing types: 1. Sealed bearings and non-sealed bearings. 2. Metal-sealed journal bearings. 3. Rubber sealed journal bearings
Cutting structure: All surfaces of the back cone and teeth are hardened, which improves the shape of the steel teeth and welding materials, showing higher teeth
Application structure: low compressive strength and high drillability softness, such as shale, clay, salt layer, etc.
All our activities have obtained ISO 9001:2008 and API certification for products and services. At the same time, mature production technology can ensure that the quality meets international requirements.

It is suitable for large-scale wells, mining, soft rock with low compressive strength and high drillability, such as shale, clay, salt formation and infrastructure applications.
The reamer is mainly composed of four or more cones. The use of high-quality tungsten carbide hard surface or high-quality tungsten carbide blade formulations and new cutting structures can improve the wear resistance of the reamer. The pilot is three cone drill bits.
Sealing and lubrication
High-performance HNBR O-ring, used for bearing seal, high-grade grease, used for lubrication.
