Abstract
A bearing, such as a rolling bearing, is mounted on a support mobile in translation and includes a lubrication mechanism. The lubrication mechanism includes at least one pipe delivering a lubricant, linked to a lubricant supply source, and at least partially engaging in the support mobile in translation to deliver the lubricant from the mobile support along an internal channel to the bearing, passing through an inner ring of the bearing.

A bearing, or a rolling bearing, mounted on a support configured to move in translation and comprising:
- a lubrication means;
- the support configured to move in translation being defined by a movable part sliding about a fixed piston of a linear-movement actuator, around which an inner ring of the bearing to be lubricated is mounted;
- the lubrication means for lubricating the bearing comprising at least one pipe for conveying a lubricant, connected to a lubricant supply source;
- and
- a conduit connected to the movable support, in which engages, at least in part, the pipe for conveying the lubricant on an internal path from the movable support to the bearing, passing through the inner ring of the bearing;
- wherein the pipe and the conduit extend parallel to the translational movement of the movable support to cooperate with each other by sliding between two extreme positions of the support, the pipe being fixed and the conduit sliding with respect thereto.
