Abstract: A seal assembly for sealing between first and second tubular members includes an annular seal body disposeable within an annular gland between the tubular members and formed of a generally compressible polymeric material. The seal body has a first axial sealing surface disposed against a first tubular member end surface, a second axial sealing member disposeable against a second tubular member end surface and a recess(es) defined partially by an angled activation surface. An annular backing ring formed of a substantially rigid material is disposed the body recess to couple the backing ring with the seal body. The backing ring has an outer axial end disposeable against the first member end surface to prevent radially outward displacement of the portions of the seal at the first member end surface and is biased axially toward the first member end surface when compression of the seal body displaces the activation surface axially.

Abstract: A seal assembly includes a generally annular primary seal member formed of a first, generally compressible polymeric material. The primary seal member has inner and outer radial ends, a first axial end disposeable against a first tubular member end surface and a second axial end disposeable against the second tubular member end surface. The first axial end has a radially-extending, generally annular primary sealing surface sealingly engageable with the first tubular member end surface. A generally annular secondary seal member is formed of a second, generally rigid polymeric material. The secondary seal member has two opposing axial ends and a radially-extending, generally annular secondary sealing surface on a first axial end. The secondary seal member is coupled with the first seal member such that the secondary sealing surface extends generally coaxially about the primary sealing surface, the secondary sealing surface being sealingly engageable with the first tubular member end surface.

Abstract: A seal assembly includes a casing coupled with a body and an annular elastomeric seal member having a base portion coupleable with a casing and a cantilever portion radially deflectable with respect to the base portion. The cantilever portion has an end connected with the base portion and a free end with sealing lip. The lip has a sealing surface extending about a centerline and is engageable with a shaft. An annular rigid tracking member is attached to the seal member proximal to the first end of the seal cantilever portion and is spaced axially from the seal lip. The tracking member has a centerline and a tracking surface engageable by the shaft outer surface so that the tracking member centerline and the seal lip centerline each remain coaxial with the shaft axis during rotation of the shaft. Further, a support member prevents axial displacement of the seal member.

Abstract: A seal and method of manufacturing same that provides increased service life and is preferably configured to provide both a dynamic seal and a static seal while demonstrating improved rigidity.

Abstract: A sleeve, rotary seal, rotary seal assembly, shaft with an integrated primary surface, rotary seal assembly component, and/or any combination thereof which preferably results in rotary seals having a higher tolerance for radial eccentricity (static eccentricity and/or dynamic eccentricity). Related methods of manufacturing, using, and/or providing same are also set forth.

Abstract: A cartridge seal for sealing a space between a housing and a rotatable shaft includes a rotary sealing member having an inner surface defining a bore for receiving the shaft and a circular outer flange extending radially outwardly from and circumferentially about a central axis, the outer flange having a radial sealing surface. A static seal assembly is disposed about the rotary member and includes an annular casing coupleable with the housing and an annular static sealing member disposed within the casing and having a radial sealing surface engageable with the rotary member sealing surface to form a sealing interface. A biasing member axially biases at least a portion of the static sealing member toward the rotary member flange. An annular collar is disposed within the casing and axially retains the rotary member within the casing such that the seal assembly is mountable on a shaft as a single unit.

Abstract: A seal assembly includes an annular static sealing member disposed within an annular channel in a housing or shaft. An annular dynamic sealing member is disposed coaxially within or about the static member and has a circumferential sealing surface engageable with the shaft or housing. An annular biasing member is disposed radially between the static and dynamic sealing members and is configured to bias the dynamic sealing member radially to maintain engagement of the sealing surface and the shaft or housing. The static member is configured to prevent relative angular displacement between the static and biasing members and the dynamic member is configured to prevent relative angular displacement between the dynamic and biasing members. As such, the dynamic sealing member, the biasing member and the static sealing member angularly displace within the channel as a single unit when torque above a particular magnitude is applied to the dynamic sealing member.
