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.

The connector assembly includes a fitting with a first mounting portion having two opposing surfaces and mounting hole(s) extending between the two surfaces for connecting with a first member. A second mounting portion extends angled with respect to the first mounting portion and has two opposing surfaces and mounting hole(s) extending between the two for connecting with a second member. A joint portion integrally connects the first and second mounting portions. One or more washers each have opposing upper and lower surfaces and at least one hole extending between the two surfaces, each receiving a fastener for attaching the second mounting portion to the second member. The washer lower surface is disposed on the second mounting portion inner surface such that the washer opening is centered about the at least one mounting hole axis. Each washer is joined to the second mounting portion to form an integral assembly.

The ball-and-socket joint member includes an inner ring, of a general shape of revolution around a first axis, having an outer surface provided with an inner raceway, an outer ring, of a general shape of revolution around a second axis, having an inner surface provided with an outer raceway, and at least one row of balls aligned circumferentially, extending radially between the inner raceway and the outer raceway. The outer surface of the inner ring comprises a portion with a generally truncated sphere shape, forming the inner raceway. The inner surface of the outer ring comprises, for each row of balls, a groove of complementary shape to that of the balls of this row, said groove forming the outer raceway.

A signaling device for signaling heating in a mechanical system susceptible to undergo contact heating during operation. The signaling device includes a body containing a thermally triggered charge generating combustion gas, ignition of the charge able to be triggered under the effect of a predetermined heat contribution, from a heating area of the body toward the charge, or under the action of an ignition command, a reservoir containing a fluid, and delivery means delivering pressurized fluid outside the reservoir through the action, directly or through an intermediate member moving in the reservoir, of the combustion gases. The signaling device also comprises at least one visual signaling element for visually signaling combustion of the charge, the visual signaling element being visible at an outer peripheral area of the signaling device after combustion of the charge. The invention also relates to a mechanical system equipped with at least one such signaling device.
