Abstract: An annular ring having a contact portion, a raceway and a squirrel-type cage secured to the contact portion. The contact portion is formed from a first metal material, and the squirrel cage is formed from a second composite-type material including a matrix in which reinforcing fibres are embedded, the pierced portion of the squirrel cage being attached to an outer surface of the contact portion. Also, a bearing assembly with rolling elements having an outer ring, an inner ring coaxial with the outer ring, and a plurality of rolling elements housed between the raceway of the contact portion of the outer ring and a raceway of the inner ring.

Abstract: A mechanical assembly including a shaft, a mechanical device providing, a bearing mounted on the shaft and including at least one ring that is able to move in rotation about the shaft, a lubrication system having a channel to allow lubricant fluid to flow, formed at the interface between the shaft and the bearing, distribution ducts for lubricant fluid, formed in the bearing and fluidically connected to the channel. The channel provides at least one constriction to create a loss of head of the lubricant fluid flowing in the channel.

Abstract: A sensor bearing assembly provides a bearing having at least one inner ring, at least one outer ring, at least one sensor installed in the bearing, at least one cable connecting the sensor to an external device, and a cable guide fixed to the bearing, into which the cable is inserted. The cable guide provides a flat part fixed to and resting on a flat housing of one of the rings of the bearing. The cable is fixed by adhesion in the cable guide, the cable guide is adhesively locked in rotation relative to the ring of the bearing to which it is fixed.
