xiros® hybrid radial ball bearing with stainless steel rings and ceramic balls

The xiros® hybrid radial ball bearing is designed for applications that demand more speed and load capacity than conventional plastic ball bearings. Stainless steel inner and outer rings are combined with lightweight silicon nitride ceramic balls and a PEEK cage to create a higher performance bearing solution capable of operating at up to 100% higher speeds than plastic ball bearings.

That is about the level I would target for these news PDPs. It gives the product a clear reason to exist and explains the material combination without padding the page with generic bearing language. The autumn news journal specifically identifies this release as a hybrid bearing using stainless steel races and ceramic balls.
