ABSTRACT:
A seal assembly engages between at least one body having an outwardly directed cylindrically annular surface centered on an axis and an annular and planar surface perpendicular to and centered on the axis and another body having an inwardly directed cylindrically annular surface centered on the axis. The seal assembly has a rigid C-section support ring fixed to the inwardly directed surface and open axially toward the planar surface, an elastomeric radial ring seal having an outer periphery vulcanized to the support ring and an inner periphery radially inwardly engaging the outwardly directed surface, and an elastomeric axial ring seal received in the support ring and engaging axially against the planar surface. Such a seal assembly is extremely compact so that it can be provided right in a roller bearing without substantially increasing its size. The radial seal can lie within the radial projection of the axial seal to give the arrangement a very short axial length.
