Abstract

A bearing includes a shaft which pivots in the bearing. The shaft includes, at at least one end thereof, a shoulder via which the shaft is in contact with an opposite surface of the bearing. The shoulder is extended by a pivot engaged in a hole provided in the bearing. The opposite surface of contact of the bearing includes at least one hollow in order to reduce the surface of contact between the shoulder of the shaft and the bearing. Application is made to the production of a bearing for a shaft of a horology movement.
