ABSTRACT:
A rotatable machine assembly comprising a sprocket with a casing defined by a pair of plates secured together and supported on a hub through a ball bearing assembly. The ball bearings are supported between an outer race member and a raceway in the hub. The plates of the casing surround and are supported by the outer race member so as to define annular axially spaced side walls on each side of the ball bearing assembly. A seal is supported by the hub on each side of the ball bearing with each seal being disposed entirely axially inwardly of the exterior surface of the respective side walls and in sealing engagement with the interior surface of each of the side walls thereby sealing the ball bearing while being protected by the side walls. Each seal includes a metal backing plate to which is bonded an integral elastomeric seal member having a plurality of lips engaging the interior surface of the adjacent side wall and an annular pad in sealing engagement with the interior edge of the circular opening in the adjacent side wall. The lips slant toward the axis of the hub and the pad portion includes a similarly slanted sealing surface engaging the interior edge of the opening in the adjacent side wall. Secondary seals are supported by the outer race member for sealing engagement with the hub means.
