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. Unsurpassed 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.

PDC bearings are very resistant to wear. Compared with traditional tungsten carbide or other hard alloy bearings, the life of diamond bearings is 4 to 10 times longer, and they can operate at high temperatures (currently the highest temperature is 233°C). The PDC bearing system can absorb excessive load for a long time, and the low friction loss in the bearing assembly further increases the transmitted mechanical power.
