  • Inquiry

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

1. Increased Bearing Life
Our exclusive cladding sustains tight tolerances and remains durable, even under extreme heat and stress.
2. Reduced Operational Costs
3. Improved Mud Motor Performance
Operators can push motors without damaging the bearings, permitting sharper turns, faster penetration and less drilling time.
4. Enhanced Drilling Accuracy
Reduced bearing wear means that design tolerances are maintained downhole, resulting in improved mud motor control and greater drilling accuracy.
5. Good Quality Standards
Zonco PDC bearings are designed and manufactured according to stringent quality standards that govern material selection, machining, infiltration brazing, surface finishing and packaging
