Abstract: The invention relates to a ring seal which comprises a main body capable of implementing a seal by static contact relative to a first cylindrical element, and a first circumferential lip capable of engaging by friction with a cylindrical surface of a second cylindrical element, said cylindrical elements being substantially coaxial and mounted so as to pivot relative to one another. The main body comprises a front surface configured to be in axial contact with a front surface of the first cylindrical element, the main body comprising a second circumferential lip radially opposite the first circumferential lip and capable of being in radial contact with a cylindrical surface of the first cylindrical element.

Abstract: A seal assembly for a component supported rotatably in relation to a further component includes a bellows, a fixed seal element, and a rotatable seal element supported in sliding contact with the fixed seal element, and the bellows is configured to generate a pressure force causing a seal effect between the fixed seal element and the rotatable seal element.

Abstract: A seal assembly is provided for sealing a space between a housing and a shaft, the housing having a bore with centerline and the shaft being disposed within the bore and rotatable about a central axis. The seal assembly includes an annular rotary seal member coupled with the shaft and having a radial rotary sealing surface. An annular static seal member is coupled with the housing, disposed about the shaft and has a radial static sealing surface disposed against the rotary sealing surface so as to prevent passage of substances between the two sealing surfaces. The rotary sealing surface is slideable against the static sealing surface as the shaft rotates about the axis and the static member is movable with respect to the housing such that the rotary and static sealing surfaces are substantially juxtaposed when the shaft axis defines an acute angle with respect to the housing centerline.
