Contact type flexible seal for bearings

A sealing device for sealing the space between relatively rotatable members comprising a rigid support element and an annular elastomeric sealing element having an internal radial annular lip extending radially and axially from an annular root portion of said elastomeric element, said annular lip having a radial section of generally V-shaped cross section with a vertex located obliquely with respect to said annular root portion of the elastomeric element and said annular lip comprising a first and a second portion of reduced cross section, said first portion corresponding to said root portion and said second portion to said vertex of the V-shaped cross section, said first and second portions of reduced cross section dividing said annular lip into first and second sections operable to engage with corresponding first and second sealing surfaces on one of said members and having sufficient flexibility to hingedly connect said sections to one another and to said root portion, said first section being tapered and extending between said root portion and said vertex and said second section being tapered and extending upwardly from said vertex.
