ABSTRACT:
A simplified method of manufacturing and assembling a unitized seal uses only three basic components, and no steps involving direct molding of elastomer to casings, or gluing or otherwise securing elastomer to the casings. Two simple, inner and outer casings have axially opposed, radially overlapping annular webs, and radially opposed, oppositely axially extending seal walls. An integral seal unit has coplanar, inner and outer disks joined at a frangible central seam. Each disk has a pair of converging seal lips disposed symmetrically to either sid of a respective seal wall. When the unit is squeezed axially between the casings during assembly, the seal walls enter between the seal lips, bottom out on the disks, break the seam, and embed the disks automatically into the casings, with no other assembly steps needed.
