Product Description

PCD radial bearings are high-performance precision bearings designed for extreme operating conditions. They consist of a rotatable inner ring and a stationary outer ring. Multiple pieces of PCD material are evenly brazed onto the circumferential surfaces of the inner and outer rings. The PCD material creates contact and sliding friction during operation, giving the bearing exceptional performance.

PCD radial bearings combine the superior properties of diamond-extreme hardness, excellent wear resistance, superior thermal conductivity, and stable chemical resistance-with the high strength and impact toughness of a carbide substrate. This enables PCD radial bearings to operate stably under high loads and complex media environments, such as those containing sand, abrasives, and corrosive acids and alkalis.
In practical engineering applications, PCD radial bearings exhibit an extremely low coefficient of friction, reducing energy loss and heat buildup. They also possess excellent compressive strength and can withstand extreme mechanical loads. They offer smooth operation and high guiding accuracy, making them key support components in many high-precision equipment.

Due to their extremely low material wear rate, PCD radial bearings can achieve a service life ranging from thousands of hours to several years, depending on the operating environment and load conditions. This feature improves overall equipment reliability while significantly reducing maintenance frequency and replacement costs.
PCD radial bearings are widely used in oil drilling, aerospace, precision machinery, chemical equipment, and other high-tech applications in harsh environments.
