Abstract
A two-piece interlocked labyrinth seal device for providing a seal between a housing and a shaft formed of two ring members connected to each other by outwardly deforming a connecting portion of the radially inwardly positioned member. The inwardly positioned member further includes a plurality of slingers to assist in slinging fluid out of the seal device and back into the housing. The system can be accurately assembled, with the ring members located very close to each other. The system has improved oil retention and water exclusion properties.
