ABSTRACT:
A slinger for use between a housing and a rotatable member passing therethrough includes an engaging member for mounting on the rotatable member, a slinger portion extending radially outward from the engaging portion, and a sealing portion generally axially extending from the slinger portion wherein the sealing portion extends radially outward when subjected to centrifugal force caused by rotation of the rotatable member to form a secondary seal. The slinger may be formed of a translucent polymer to facilitate a visual inspection of a primary seal located behind the slinger.
