The rotor includes an annular body rotatable about a central axis and including radially inner and outer rings. The annular body includes an intermediate portion connecting the radially inner and outer rings and spacing the radially inner ring in a first direction from a base portion of the annular body. The annular body further includes a pocket formed at least in part by the intermediate portion and a snap-fit portion axially intermediate the base portion and a free end portion of the radially inner ring. The snap-fit portion of the annular body is configured to form a snap-fit connection with a snap-fit member of a slinger that extends into the pocket.

Roller bearing seal assembly

In accordance with one aspect of the present disclosure, a roller bearing seal assembly is provided that includes a seal case and a rotor having a unitary, one-piece construction. The rotor is connected to the seal case and is rotatable relative to the seal case about an axis. The seal case and rotor include interfering portions that limit axial separation of the rotor and the seal case. In one embodiment, the rotor and seal case include at least one snap-fit connection that permits the rotor and seal case to be readily assembled. The at least one snap-fit connection includes the interfering portions which inhibit axial separation of the rotor and seal case after the rotor and seal case have been assembled.
