An auxiliary sealing structure for a shaft bearing having a housing, in which a segmented collar is adapted to be clamped onto the end of the bearing housing using interlocking opposite facing shoulders on the housing and collar. The two segments of the collar are secured together to clamp the shoulders into interlocking relationship and thereby secure the auxiliary seal on the end of the housing. The collar contains an annular groove or recess in which a seal is seated, the seal being either of the labyrinth or gasket type. Various configurations for the two oppositely facing shoulders on the housing and collar may be used; however, tapered shoulders are preferred, which result in a firm securing action between the housing and collar when the bolts or other securing means connecting the collar segments are tightened.
An auxiliary sealing structure for a shaft bearing having a housing, comprising a collar having two sections for encircling a shaft and having an inwardly facing recess, a seal disposed in said recess for engaging the surface of the shaft, an outwardly radially facing shoulder on the end of the bearing housing, an inwardly radially facing shoulder on said collar for engaging the shoulder on the housing, and means interconnecting said collar section for securing said shoulders together and retaining said collar on the end of the bearing housing.
