ABSTRACT:
A sealing assembly for a device having a rotatable shaft. The sealing assembly includes a stationary seal in association with the device having an opening generally conforming to the rotatable shaft together with a rotatable seal adapted to engage and cooperate with the stationary seal for effecting a seal therebetween. The rotatable seal is adapted to be mounted on the rotatable shaft for rotational movement therewith and includes a collar having an opening generally conforming to the rotatable shaft. The opening in the collar is defined by a normally undersized shaft-confronting surface and the collar is split through the opening along a diameter to include a pair of substantially identical portions. The sealing assembly also includes a spacer formed of a flowable material adapted to be disposed between the substantially identical portions of the collar for sealingly conforming the collar to the rotatable shaft within a normal tolerance range for rotatable shafts. With this arrangement, the substantially identical portions of the collar are secured together in engagement with the rotatable shaft to cause the flowable material of the spacer to fill any gaps between the collar and the rotatable shaft.
