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. |
