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.
