Abstract: A brake shaft of a vehicle is rotatably supported in a housing by a pair of bush assemblies acting as plain bearings. Each bush assembly is composed of a cylindrical body with grooves in its inner periphery which open to one end of the body. The housing has a bore for introducing lubricant into the grooves. A flange at the opposite end of each body has a recess in which a multi-lip seal is fitted. The housing has recesses which receive the flanges, of the bodies and deformable lips on the bodies locate in the recesses and assist the seals to prevent the ingress of contaminants.

Abstract: A roller bearing comprising inner and outer annular ring members having confronting inner and outer spaced raceways, the inner ring member having an integral flange confronting the axial ends of the rollers of one row, at least a pair of rows of rollers separated by cages and in line contact with said bearing raceways, a guide flange confronting and guiding the rollers of the other row at the opposite axial end of the inner annular member, sealing means fastened at said one axial end to said outer annular member, characterized in that said guide flange is formed by a substantially cylindrical bearing component fixed in place by a detachable retaining member.
