V-rings are flexible rubber seals that stretch-fit onto the shaft and rotate with the shaft against a counter face.  They are specifically designed to protect the primary seal from contaminants. These seals are …More Info not designed to seal pressure differentials or to seal against fluid levels; they are primarily for contaminants exclusion. The seal design utilizes centrifugal force to prevent intrusion of contaminants into the bearing chamber.
