PDC Radial Bearings :
From standard cutters to custom drilling solutions, we provide the industry's most reliable PDC products for extreme conditions.
Radial bearings are a type of mechanical bearing that support loads primarily acting perpendicular to the shaft's axis. They allow for rotation or linear movement while minimizing friction between the moving parts. Radial bearings are commonly used in various applications, including motors, engines, and machinery, to help smoothen operational performance by facilitating the movement of rotating components.
PDC radial bearing is composed of a rotating inner ring and a fixed bearing outer ring, and a series of PDC composite cutters are brazed on the circumferential surface respectively. During operation, the PDC surfaces of the inner and outer rings of the bearing rub against each other. With very low friction, high hardness, high wear resistance, high thermal conductivity, and corrosion resistance, PCD radial bearing is especially suitable for process fluid sand abrasive particle lubrication, acid-base environment, and other harsh working conditions. The radial bearing can withstand high loads during operation. Due to the low wear rate, the service life of PCD bearings ranges from 1000 hours to years, depending on the application.

PDC radial bearings are a widely used type of bearing in mechanical engineering. They primarily consist of a thin-walled stationary ring and a matching rotating ring. As load-bearing components, their wall thickness is relatively thin, typically within a few millimeters. The overall structure of PDC radial bearings is highly compact, making them ideal for mechanical equipment with limited space, where they effectively meet installation space requirements.
