Abstract: The seal assembly comprising a fixed element, a rotating element, and a seal member comprising a stiff annular reinforcement and a seal of an elastic material and in contact with a sliding surface. The sliding surface has an arithmetic mean roughness greater than or equal to 0.15 ?m and less than 0.5 ?m. The sliding surface has a roughness ratio greater than or equal to one. The roughness ratio is the ratio of a first parameter corresponding to a quantity of valleys to a second parameter corresponding to a quantity of peaks over the sliding surface.

Abstract: This anti-vibration mount, comprising a base and a head connected by an elastomer body, is intended to be interposed between two rigid elements to damp the vibrations between these two elements, on a central axis. This mount comprises a non-extensible limiting cable forming a loop, which is fixed to the base and to the head, this cable comprising a first part which is supported on the head by winding around it and which extends towards the base from the head, and a second part which runs along at least a first portion of the periphery of the base and winds around at least a first return element integral with the base, level with two joints between this second part and the first part of the cable, the cable being restrained by the return element.

Abstract: A hydraulic antivibration support has two rigid strength members with at least the first strength member having an aluminum body. The strength members are connected to each other by an elastomer body which defines a first hydraulic chamber belonging to a liquid-filled hydraulic assembly, said hydraulic assembly being closed in sealed manner by a closure element crimped by means of a steel insert which is partially embedded in the aluminum body of the first strength member.
