PDC bearing

 

The advantages of artificial diamond lie in hardness, thermal conductivity, strength, toughness and wear resistance. Diamond bearings can be used to study underwater power generation technology.

 

Because the hardness of diamond powder is higher than that of single crystal diamond and it is not easy to break, diamond bearings are made of sintered diamond powder, and cobalt and tungsten carbide are also conducive to improve the hardness of bearings, but also ensure that single crystal diamond can be attached to the stainless steel ring.

 

Because diamond bearings have the characteristics of low friction coefficient and high load rate in air, oil and water, some technical aspects need to be improved compared with stainless steel bearings. In the future, diamond bearings will be widely used in drilling tools and equipment for oil and natural gas, as well as in equipment that uses flow or tidal energy turbines to generate electricity.

 

PDC bearings offer simple mud lubricated bearing systems and diamond durability and strength. PDC thrust bearings provide a high-performance, durable solution for drilling tool manufacturers who are not satisfied with the limited service life and carrying capacity of traditional bearings.

 

PDC thrust bearing is widely used in turbine drill, mud motor and other oilfield applications. Compared with tungsten carbide bearings, PDC bearings have longer working life, which is 4-10 times that of tungsten carbide bearings, and can also withstand increased load capacity. PDC thrust bearing production characteristics, high hardness, high wear resistance, high corrosion resistance, longer service life.
