Tapered roller bearing Wikipedia

Description. The inner and outer ring raceways are segments of cones and the rollers are tapered so that the conical surfaces of the raceways, and the roller axes, if projected, would all meet at a common point on the main axis of the bearing. This geometry makes the motion of the cones remain coaxial, with no sliding motion between the raceways and the OD of the rollers.

Cone Pivot vs. Conical Pivot WatchUSeek Watch Forums

Hi all, not a technical queston, more a matter on nomemclature: Is there a popular term for balance bearings with pointed staffs? See why I prevented the term conical: Britten calls them "cone pivots" (geometrically correct), but he calls the normal capstone pivots with chamfered shoulder "conical" (geometrically dubious). Timex calls them Vcone bearing, but this is likely a sort of trademark.
