Top Grade Steel Grade PDC Radial Bearing Excellent Thermal Shock Resistance

Excellent thermal shock resistance PDC Radial Bearing used for internal drilling tool components

Polycrystalline Diamond radial bearings are comprised of a series of PCD inserts assembled (usually by brazing) in carrier rings. A typical PCD radial bearing set includes a rotating and stationary bearing ring. These two rings oppose each other with the PCD surface on the inside diameter of one ring in direct contact with the PCD surface on the outside diameter of the mating ring.

The ultra-high hardness and strength of PCD allows Seed Bearings' radial bearings to sustain very high loads during operation. In addition, they wear at a very low rate, resulting in the PCD bearings lasting from 1000 hours to many years, depending on the application. These PCD inserts also utilize the highest quality steel grade available.

1. Product Introduction of PDC Thrust bearing

PDC Thrust Bearing is widely used in turbo drills,mud motors and other oil field applications. We have two different types includes PDC radial bearing and PDC thrust bearing.Compared with tungsten carbide bearing,The PDC bearing has longer working life,its life is 4-10 times longer than tungsten carbide bearing, meanwhile it can also bear the increased load capacity.

2. Product Specification of PDC Thrust bearing

The bearings are available in size from 1inch to 10inch in diameter.

We can make PDC Radial bearing and PDC Thrust bearing as your specific drawings or samples.

·Highly resistant to abrasion, erosion, corrosion, and mechanical failure

·Extremely resistant to chipping, cracking, and flaking which are inherent problems in cladding or welded overlay processes

·High heat conductivity eliminates thermal cracking

·Proprietary design eliminates catastrophic downhole radial bearing failure

·Carbide tile and matrix design ensures extended life compared to cladding or welded overlay designs

·Inner and outer components can be reconditioned.

PDC Radial bearings support the radial and bending loads on the drive shaft. To this end, we have developed a proprietary hard-facing process for maximum protection against radial wear. This has resulted in high performance figures of about 10-20 times longer than figures recorded using typical tungsten carbide cladded bearings.
