A radial lip seal includes a sealing lip body having a contact point defining an inner diameter of the radial lip seal, and a heelstock body defining an outer diameter and having a supporting section arranged radially inwardly relative to the outer diameter and extending along a boundary of the sealing lip body toward the contact point. The heelstock body is formed of a heelstock material that is flexible, and the heelstock material is stiffer relative to a material of the sealing lip body.

A method of manufacturing a sealing component includes defining a configuration for the sealing component, wherein the configuration comprises a cross-section comprising a first wall and a second wall joined by a turning wall to form a generally U-shape, the first wall and the second wall comprising a variable cross-sectional thickness, wherein the cross-section is taken along a plane extending along an axial axis of the sealing component and the cross-section extends in a circumferential direction. The method also includes depositing a powder into a chamber, applying an energy source to the deposited powder, and consolidating the powder into a layer according to the defined configuration.

The present invention provides a sealing member which includes a substrate including silicon carbide; and a plurality of cylindrical or polygonal columnar graphites dispersed in the substrate, and a method for manufacturing the same.

A system for processing elastomeric load rings may include an elastomeric load ring defining an initial width. The system may also include a fixture assembly configured to receive the load ring between first and second clamp members. The second clamp member may be spaced apart from the first clamp member such that a gap is defined between the clamp members when the load ring defines the initial width. The fixture assembly may also include a load member configured to apply a compressive load through the first clamp member and/or the second clamp member such that the load ring is compressed between the clamp members. When the load ring is heated, a spring force of the load ring may be reduced as the load ring is compressed between the clamp members such that the initial width of the load ring is reduced to a final width.

A seal assembly for a bearing housing is provided. The seal assembly may include a rotor seal member configured to be in sealing engagement with a rotary shaft. The seal assembly may also include a stator seal member formed from a plurality of stator seal member segments and configured to be in sealing engagement with the bearing housing. The stator seal member may also include an annular stator outer surface configured to be disposed on an inner surface of the bearing housing in sealing engagement therewith, and an annular stator inner surface radially opposing the annular stator outer surface and forming a first stator inner annular groove configured to receive the rotor seal member therein and form a sealing engagement therewith.

A method for making a valve stem seal, comprising the steps of providing a metal retainer having a top portion and a body portion. The body portion having a first section and a second section. In a first state, the first section of the body portion is cylindrical and the second section of the body portion is cone shaped. Providing a hollow mold. Inserting the metal retainer into the outer mold piece, inserting the inner mold piece into the metal retainer, and then securing the inner and outer mold pieces to each other. Filling a cavity around the top portion of the metal retainer with an elastomeric compound. Removing the metal retainer and the formed rubber sealing element from the mold pieces, and pressing downward over the formed valve stem seal to compress the second section of the body portion radially inwardly.
