A sealing apparatus includes: an annular reinforcement ring around an axis; and an annular elastic body part around the axis, which is attached to the reinforcement ring and is formed of an elastic body. The elastic body part has: a side lip, an intermediate lip, and a grease lip. A grease as a lubricant is applied to respective inner peripheral side surfaces of the side lip, the intermediate lip, and the grease lip. A thickener of the grease includes no urea-based thickener. In a usage state of the sealing apparatus, a cross sectional area of an inter-lip space enclosed by the side lip, the intermediate lip, and a hub ring is equal to or greater than 3.5 mm.sup.2.

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 bearing seal includes at least one first metal-plate element having an attachment region for attaching the first metal-plate element to a bearing inner ring, at least one seal element attached to the first metal-plate element, and at least one spring element configured to press at least one region of the seal element in a radially outward direction. Also a wheel bearing assembly including the bearing seal.

A seal assembly includes an outer annular case disposed within and coupled with a rotatable outer member to be angularly displace about a central axis. An annular flexible seal is disposed within and coupled with the case to angularly displace about the central axis when the outer member rotates about the axis. The flexible seal has elastomeric sealing lip(s) engageable with an outer circumferential surface of the shaft or of a sleeve disposed about the shaft. An annular inner rigid seal is disposed within the outer case and has an inner end coupled with the shaft or the sleeve, the flexible seal being radially displaceable with respect to the inner rigid seal. An outer annular rigid seal is disposed about the inner seal and has an inner end sealing against the inner rigid seal. A biasing member biases the outer rigid seal against the inner rigid seal.

In a sealing apparatus, a lip tip portion of a seal lip of an elastic body part is defined by a sealing side surface and an atmospheric side surface, connected through a lip tip with each other. The lip tip portion includes a circumferential projection and a screw portion on the atmospheric side surface. The circumferential projection extends parallel to the lip tip. The screw portion includes a plurality of parallel screw projections and a plurality of bilge screw projections. The parallel screw projections are arranged at equal pitch intervals in parallel with each other between the lip tip and the circumferential projection. The bilge screw projections are arranged at equal pitch intervals in parallel with each other from the circumferential projection toward the atmospheric side. The bilge screw projections do not overlap the adjacent bilge screw projections in a direction of axis with each other.

A flexible double lipped annular seal includes an anchor segment at a radially outermost portion thereof and having a pocket formed therein. The annular seal includes a branch segment extending axially outward and radially inward from the first leg at an angle. A first lip seal and a second lip seal extend radially inward from the branch segment and have a gap therebetween. The branch segment terminates in a stub segment. The annular seal includes a metallic shield secured to the annular seal and a portion of which seats in the pocket.

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.
