Abstract: A unitized seal incorporates two nested steel casing, a PTFE disk with two edges in sealing contact with one casing, and an elastomer seal with two lips in sealing contact with the back of the PTFE disk. The PTFE disk provides two primary, low friction sealing barriers. The elastomer seal provides two additional barriers, which comply more readily than the edges of the stiffer PTFE disk to radial eccentricity and axial run out. The elastomer seal lips run with reduced friction because of the fact that they contact the PTFE disk.

Abstract: A bearing bushing is provided with a sealing ring having a conical bore surface on the side remote from the side at which a shaft is inserted. The rim of the bearing bushing is provided with a concial surface which cooperates with the conical surface of the sealing ring during insertion of the shaft so as to restrain the sealing ring in a manner that prevents it from being forced out of the bearing bushing. Alternatively, a restraining ring having a circumferential projection with a conical surface can be arranged to prevent unseating of the sealing ring when the shaft is inserted from the sealing ring side of the bearing bushing. A shaft being inserted exerts axial force on the sealing ring, causing the inner portion of the sealing ring to expand radially as the conical surface of the sealing ring slidingly ascends the conical surface of the bushing rim or restraining ring, thereby allowing easy insertion of the shaft.
