A sleeve for a lip seal assembly includes a rigid portion with a tubular section having an inner surface defining a bore for receiving a shaft and an outer surface providing a seal engagement surface, and a radial flange extending from an axial end of the tubular section. An elastomeric portion attached to the rigid portion has a tubular section disposed within the rigid portion bore and a lip extending axially outwardly from one axial end of the tubular section so as to be disposed externally of the rigid portion bore and having a sealing surface engageable with the shaft outer surface, and may have another lip extending axially from the opposing axial end. The axial lip(s) reduce installation forces, retain lubricant within the sleeve bore during shipping, handling, test shaft and plug installation and removal, and final shaft assembly, and the air side lip prevents leakage of assembly lubricant.

Sleeve for a seal assembly

A seal assembly for sealing a space between a shaft and a housing includes a seal having a central axis, an inner annular sealing lip sealingly engageable with the shaft and an outer annular rim with an outer circumferential surfaces engageable with the housing inner surface. At least one and preferably two support members are disposed within the annular rim and at least one and preferably a plurality of adjustment devices are coupled with the support members. Each adjustment device is configured to displace at least a portion of each support member radially outwardly with respect to the central axis, to displace at least a portion of the rim generally toward the housing inner surface, and/or to displace at least a portion of each support member radially inwardly toward the central axis to permit displacement of at least a portion of the rim generally away from the housing inner surface.

Seal assembly with adjustable outside diameter

A sealing device is provided for sealing a space between a hub and a spindle pivotally connected by a bearing, the hub being coaxially mounted on the spindle and extending in an axial direction and the bearing having an inner ring. The sealing device includes a radial shaft seal including a shell portion having an outer static sealing surface disposeable against the hub and a hinge portion having a radial sealing lip. A sleeve member includes an inner static sealing surface disposeable against the spindle, a running surface contactable by the sealing lip and a sleeve portion. The sleeve portion extends in the axial direction beyond a side surface of the bearing inner ring and is disposeable about a shoulder diameter of the bearing inner ring.
