Products Description
Hope can provide PDC for Bearings and PDC Radial Bearings.
PDC for Bearing are engineered for downhole thrust and radial bearing systems in oil and gas drilling applications. Made with high-quality polycrystalline diamond and a tungsten carbide substrate, they provide excellent wear resistance, low friction, and high load-bearing capacity. These inserts ensure stable operation, extended service life, and reliable performance under high temperature, high pressure, and abrasive drilling conditions.
PDC Radial Bearing consists of a rotating inner ring and a fixed outer ring, with PDC composite cutters brazed on their circumferential surfaces. During operation, the PDC surfaces rub against each other, providing very low friction along with high hardness, wear resistance, thermal conductivity, and corrosion resistance. This makes PCD radial bearings ideal for abrasive, sand-laden fluids, acid–base environments, and other harsh conditions. They can withstand high loads, and due to their low wear rate, service life ranges from 1,000 hours to several years, depending on the application..
Our Advantage
PDC Radial bearings
1.Highest wear and impact resistance PDC cutters.
2.Hardest known stainless base.
3.Ultra-high accuracy and finish.
TSP Radial bearings
1.High load capacity and reduced frictionimproved efficiency, and lower energyconsumption in machinery.
2.Durability,temperature resistance corrosion resistance
TC Radial bearings
1.Highly resistant to abrasion, versioncorrosion,and mechanical failure.
2.Extremely resistant to chipping, cracking, and flaking.
3.High heat conductivity eliminatesthermal crackin.
We look forward to hearing from you with precise drawings and detailed requirement to make the reasonable quotation!
