A continuous length of formed metal retaining material can be cut to the partial or full circumference or perimeter of at least one assembly component and disposed in a groove of at least one assembly component to form a retaining ring engaging at least one other assembly component. The retaining ring prohibits lateral and rotational movement.

A multi-layered lip seal comprising a dynamic layer optionally having a filler incorporated therein and a static layer optionally having a filler incorporated therein is described. The lip seal has an annular ring shape, wherein an inner diameter of the ring shape is curved in an axial direction so as to give the lip seal a J-shape when viewed from a cross-sectional perspective. Fillers that can be included in static layer include stiffening filler, reinforcement fillers, conductive fillers and/or abrasion resistance fillers. Fillers that can be included in the dynamic layer include wear resistance fillers. The use of specific fillers in specific layers of the multi-layered lip seal allows for certain segments of the lip seal to be imparted with the benefits of the filler without negatively impacting other segments of the lip seal.

A shaft seal assembly comprises a stator configured to engage a housing and a rotor positioned within the stator. The stator may include a main body, a stator inward radial projection extending radially inward from the stator main body, and a collection groove adjacent the stator inward radial projection. The rotor may include a rotor main body and a rotor axial projection extending from the rotor main body. The rotor axial projection may be positioned adjacent a distal end of the stator inward radial projection.

A retainer device is for a seal assembly for sealing between a shaft rotatable about a central axis and a housing having a bore. The seal assembly includes at least one annular seal disposed within the housing bore and about the shaft and at least one spring for biasing the seal along the axis. The retainer device includes a generally annular body disposeable within the housing bore so as to be spaced axially from the at least one seal. The body is coupleable with the housing such that the body is generally nonrotatable about the central axis and includes at least one retainer lug extending at least generally axially from the body. The lug is engageable with the seal to prevent angular displacement of the seal about the axis. The body has at least one generally radially-extending spring contact surface contactable by an end of the at least one spring.

Floating seal assemblies having a seal element, a support band, and at least two loading springs that produce different spring forces to apply different sealing loads at the first and second sealing flanges of the seal element. The seal assembly is without a locking ring to enable the seal assembly to float along an axis of one of the components to be sealed. The different sealing loads allow the seal assembly to grip against one surface to prevent relative rotation and to enable sealing and relative rotation with another surface.

A method for refurbishing an assembly having a first component and a second component is provided. The first component has a fore portion welded to the second component and a flared aft portion in proximity with the second component. The method includes processing the assembly such that the flared aft portion and a part of the fore portion proximal to the flared aft portion of the first component is subject to peening until the flared aft portion is plastically deformed from an initial position to a desired final position with respect to the second component.
