Abstract
Abstract A bearing, joint or knuckle, e.g. between a steering rod and a lever or arm connected to a wheel in an automotive stearing linkage, is provided with an inner and/or an outer metal shell or sleeve to which a rubber layer is vulcanized, the force being transmitted between the inner surface and the outer surface of the joint through elastic deformation of the elastomeric layer. One or both of the shells is, according to the invention, slotted parallel to generatrices of the shell.
