Abstract

A seal assembly (12) is described for sealing between a shaft (2) and a housing (3). The seal assembly is positioned in an annular region (7) between the shaft and the housing. The seal assembly comprises at least a pair of lip seals (1, 1') that are arranged within the annular region. Each lip seal comprises an energising ring (4) which is partially encapsulated within an annular jacket (5). The jacket of each lip seal further has a lip-shaped part (6) for engagement against one of the shaft or housing. The at least one pair of lip seals are arranged spaced in a radial direction of the shaft. A first of the lip seals provides an inner lip seal (13) where its lip- shaped part seals against the shaft (2), and a second of the lip seals provides an outer lip seal (14) where its lip-shaped part seals against the housing (3). The seal assembly may comprise several pairs of lip seals, and these may be energised collectively through tightening a compression ring (9).
