A lubricator comprises a container of variable volume holding a lubricant and having an opening for dispensing the lubricant. An electromechanical or electrochemical actuator operated by a control circuit makes it possible to reduce the volume of the container. An electrical circuit for displaying the state of the lubricator comprising a light source can emit at least one alarm light signal. A lid affixed to the container in a removable manner constitutes a housing for the electrical signal display circuit and defines a reference axis of the lubricator. A light diffuser guides the light emitted by the light source towards numerous light outlets distributed along the circumference of the lid in a manner that at least one of the light outlets is visible regardless of the position of an observer facing the lubricator and is located on a circle of observation centered on the reference axis of the lubricator.

A suspension stop for a motor vehicle has an upper cup, a lower cup and roller bodies arranged between the cups to permit the relative rotation thereof. The cups are designed to have at least one annular space between them. The stop further has a seal element arranged in the annular space with a sliding contact with each cup. The seal element is arranged to be mobile with relation to at least one cup.

A roller bearing includes a plurality of conical roller bodies arranged between inner and outer rings, and a cage having an annular sectional body mounted between the inner and outer rings. The annular sectional body further having an annular oil thrower located on each transverse side, each oil thrower having internal and external radial projections, wherein the free end of each projection is positioned opposite and away from a corresponding one of the inner and outer rings. The bearing has functional axial and radial clearances between the internal and external radial projections and the internal and outer rings. The clearances facilitate the passage of a bearing lubrication fluid there through and form an obstacle to the passage of solid particles.

A roller bearing for the rotational guidance of a motor vehicle wheel, the bearing comprising a rotating inner member, a fixed outer member and rolling bodies allowing their relative rotation about an axis. The inner member includes a bore on the periphery of which flutes are provided so as to allow the rotational coupling of a fluted shaft with the internal member. The bearing has a path forming an air passage having an outer channel and an inner channel designed to pass right through respectively each of the members, in which, in combination, the path has a groove formed by the omission of at least the front part of at least one flute, from an intermediate zone of the bore as far as its front face. The downstream end of the inner channel opens out in the groove.
