A rolling bearing includes an outer ring, an inner ring, a plurality of rolling bodies, and a seal member. An outer peripheral portion of the seal member is fixed by a retaining ring to a groove portion formed on an inner peripheral surface of the outer ring and an inner peripheral portion of the seal member is elastically deformable. The seal member includes an inclined portion. 1≤Ts/Sct≤10 is satisfied when Ts is a circumferential gap of the retaining ring at a time when the seal member and the retaining ring are attached to the groove portion of the outer ring and Sct is an axial thickness of a part of the seal member in contact with the retaining ring.

An outer peripheral portion of the seal member is fixed by a retaining ring to a groove portion formed on an inner peripheral surface of the outer ring and an inner peripheral portion of the seal member is elastically deformable. The seal member includes an inclined portion. The seal member satisfies 0.25≤Skn/Skt≤2.5 when Skn is a radial length from an inclination start part of the inclined portion on an inside in an axial direction to an outermost diameter position of a part of contact of the seal member with an outer peripheral surface of the inner ring and Skt is a thickness of the inclined portion in a direction perpendicular to an inclination direction.

A sealing ring includes: a sealing body of a rubber-elastic sealing material; and an intermediate element which is connected to the sealing body. The sealing body includes a retaining collar which delimits an undercut. The intermediate element is arranged in the undercut and assigned to the retaining collar in a non-adhered and non-destructively detachable manner.

A rotary sealing arrangement comprises a housing, a shaft mounted for rotation within the housing about a shaft axis (A) and a rotary seal provided between the housing and the shaft. The rotary seal comprises a static seal element mounted to the housing and a rotary sealing element mounted for rotation with the shaft. The static seal element comprises a mounting part and a flexible lip seal extending from the mounting part in an axial direction relative to the shaft. The rotary seal element comprises a seal body comprising an axially facing sealing face. The lip seal resiliently engages the sealing face of the seal body. The static seal element and the rotary seal element are mounted such that the relative axial positions of the static seal element and the rotary seal element can be adjusted.

A seal comprising: an annular body defining an inner sidewall and an outer sidewall extending from a base; and a plurality of energizing elements disposed within a recess between the inner and outer sidewalls, wherein at least two adjacent energizing elements of the plurality of energizing elements have different unit loads as compared to one another, and wherein the at least two adjacent energizing elements contact the inner sidewall.

Provided is a gasket mounting structure capable of preventing a gasket from being mounted in a wrong direction. The gasket mounting structure is configured such that, when a jig 200 is inserted into a gasket 100 from a large-diameter inner peripheral surface portion 124 side, a small-diameter outer peripheral surface portion 210 is press-fitted into an inner peripheral surface of a seal projection 122 to result in a state in which the gasket 100 is held by the jig 200 and, when the jig 200 is inserted into the gasket 100 from a small-diameter inner peripheral surface portion 123 side, the small-diameter outer peripheral surface portion 210 does not reach a position at which the small-diameter outer peripheral surface portion 210 can come into contact with the seal projection 122.

An exemplary embodiment, among others, of the present disclosure is directed to a drain closure assembly. Such an assembly has a head of the drain closure assembly that is fastened to a top end of a stem, wherein the bottom end of the stem is insertable in a drain shoe. The assembly further includes a gasket fastened around an outer cylinder of the stem below the head. Accordingly, the gasket comprises a series of concentric annular platforms such that a force applied to a top surface of the gasket causes an upper concentric annular platform having a smaller outer diameter to be compressed before the lower concentric annular platform having a larger outer diameter is compressed, thereby creating a seal between the head of the drain closure assembly and the drain shoe.
