Abstract: A plain bearing having an outer ring and an inner ring, the outer ring and the inner ring providing respectively an inner surface and an outer surface intended to cooperate with each other for the relative movement of the outer and inner rings, the inner surface of the outer ring and the outer surface of the inner ring each including a coating including at least one layer. The hardness of the coating on the inner surface of the outer ring is less than the hardness of the outer ring, and the hardness of the coating on the outer surface of the inner ring is greater than the hardness of the inner ring.

Abstract: A contact layer is formed by a deposition method on an inner surface of a first metal element by a centrifuging process, and preferably includes an inner layer of copper alloy and an outer layer of tin alloy. Such a contact layer is used in an articulation joint including a first metal element having a surface provided with the contact layer, and a second metal element with a second surface. The first and second elements are relatively movable such that first and second surfaces slide against each other.

Abstract: A spherical ball joint having an inner ring and an outer ring that cooperate by way of respective truncated spherical contact surfaces, the inner ring having a central bore with a cylindrical bore portion. The spherical ball joint includes a cylindrical sleeve mounted securely in the cylindrical bore portion, the sleeve configured to be mounted around a shaft, the sleeve being made of a wear-resistant material different from that of the inner ring.

Abstract: A method of determining an amount of wear in a spherical working surface of a bearing ring of a spherical plain bearing, the method including providing a reference groove of predetermined depth in an unworn working surface, using the reference groove and axial end faces of the bearing ring as reference surfaces for centering and aligning a measuring tool. The tool having a first surface, and a protrusion that extends from the first surface in radial direction and is adapted to fit into the reference groove and two or more radial openings that extend from a second surface of the tool. Determining the amount of wear by measuring the radial distance to the spherical working surface through each of the radial openings and comparing the measured value with a reference value measured using the tool for an unworn working surface comprising a reference groove of the same predetermined depth.
