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 method for predicting the evolution of a defect of a bearing includes identifying a defect of the bearing and extracting geometrical parameters of the identified defect by a trained deep learning algorithm from a picture of the bearing and further includes predicting an evolution of the identified defect of the bearing from a type of the identified defect and the extracted geometrical parameters of the identified defect, from operating parameters of the bearing and from a model of the bearing. Also a device for performing the method.

Abstract: A bearing element of a bearing unit includes a substrate, a first coating on the substrate and a second coating on the first coating. The first coating is configured to increase a wear resistance of the substrate and includes a first solid lubricant, and the second coating is softer than the first coating and includes a second solid lubricant. The solid lubricants of the first and second coatings may be MoS2, and the first coating may include between 3 and 30 at % Ti.

Abstract: A landing bearing for use in a magnetic bearing assembly is provided. The landing bearing includes a first landing surface configured to be mounted on a shaft and a bushing having a second landing surface configured to be mounted in a housing or in a stator coaxially with the landing sleeve. The second landing surface is arranged so as to face the first landing surface. It is proposed that at least one of the first landing surface and the second landing surface is provided with at least one recess for receiving lubricant.

Abstract: A reciprocating piston lubrication pump with a component is proposed having an opening, which has at least one cylinder-shaped part, and with at least one piston, which comprises a radially outer surface built at least partly by a coating. A clearance between the radially outer surface of the piston and the component is between 1 μm and 20 μm when the radially outer surface is positioned in the cylinder-shaped part. The surface hardness of the coating at the radially outer surface is 2 to 10 times higher than that of a region of the component, which forms the cylinder-shaped part.

Abstract: A rolling-element bearing assembly includes a rolling-element bearing and an oil conditioning system for conditioning oil used to lubricate the bearing. The bearing has an inner ring and an outer ring and a plurality of rolling elements rotatably disposed between the inner ring and the outer ring. The bearing includes openings for discharging oil from the bearing and for introducing oil into the bearing, and the openings are connected to the oil conditioning system. A raceway of the inner ring and/or a raceway of the outer ring is coated with a first coating, and the rolling elements are at least partially coated with a second coating that is different from the first coating.
