Abstract
A shaft seal assembly for use with a reciprocating or rotating shaft includes a shaft seal, a lubricant-storing ring, and a retainer. The retainer and ring can be formed as a subassembly and then combined with a shaft seal. The assembly provides a lubricated shaft and seal that improves the effective life of the shaft seal.
