High-Performance Tungsten Carbide PDC Bearings – Extend Drilling Tool Life | ZZCT

PDC bearings and tungsten carbide bearings are the key wear parts of oil&gas directional drilling downhole tools, so the wear resistance of the bearings is directly related to the life of the drilling tool. 

There are two production processes we have for TC bearings, one is sintering process, and the other is surfacing process; the bearing that use surfacing process is more cost-effective and the service life is more than two times of that of bearing use sintering process.  

Armour cladding is a PTAW(Plasma Transfered Arc Welding) overlayer with extra wear resistance and very high impact resistance. Our
proprietary cladding technology is the best wear protection available for downhole tools and wire steel metallurgy equipment,
including mud motor bearings, flow restrictors, and guide rollers.
- Bearing is custom engineered and designed to meet a customer's specific requirement. Every bearing is precision ground to size
and held to a tight tolerance. Engineering services are available to assist with creating a customized bearing for a specific tool or application.

- Cladding can be applied to most alloy steels, carbon steels, precipitation hardened steels, and stainless steels, please refer
the major properties and features here below in the table.

Mud motor is one of the most widely used downhole tools in oil directional drilling, in which TC Bearing is the most important parts. Century Tool adopt advanced vacuum sintering process and HIP sintering process to perfectly combine sintered cemented carbide layer and steel body of Tc bearing ,significantly enhance its resistance to abrasion,erosion and corrosion from mud fluid in drilling mutor,thus ensure that downhole motor could stably work in directional drilling. Compare to TC bearing, PDC bearing is a more innovative design in downhole mud motor which Century Tool could also supply and welcome to consult!
