Ceradyne perfected its silicon nitride and high-volume machining technology for automotive cam roller applications. This same expertise has been used to produce rolling elements for cylindrical roller bearings. Ceradyne’s rollers have precision-machined crowned profiles designed to minimize stresses in the ceramic and metallic components.

Silicon nitride allows cylindrical roller bearings to run at higher speeds with reduced friction leading to increased reliability and longer life. Ceradyne’s silicon nitride roller manufacturing technology allows bearing designers to advance the state of roller bearing technology in a similar manner that silicon nitride balls are revolutionizing the ball bearing industry.
