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.

Disclosed is a cooling system comprising a refrigerant cycle for cycling refrigerant from at least a compressor unit for com-pressing gaseous refrigerant to a condenser unit for condensing gaseous refrigerant to liquid refrigerant, from the condenser unit to an evaporator unit for evaporating the liquid refrigerant to gaseous refrigerant, and from the evaporating unit back to the compressor unit, and a lubrication cycle having at least one lubricating refrigerant supply line for providing refrigerant as lubricant to a bearing assembly, wherein the at least one lubricating refrigerant supply line branches off from the refrigerant cycle at the condenser unit for providing refrigerant to the bearing assembly, and re-unites with the refrigerant cycle at the evaporator unit, for feeding back refrigerant from the bearing assembly to the refrigerant cycle.

Cooling system and method for operating a cooling system

A cooling system and methods of employing the same includes a refrigerant cycle for cycling refrigerant from a compressor to a condenser and from the condenser an evaporator unit, and a lubrication cycle having at least one lubricating refrigerant supply line for providing refrigerant as lubricant to a bearing assembly.

A bearing component of a rolling element bearing, such as a rolling element, a bearing ring, and/or a cage for retaining rolling elements of a rolling element bearing, has an outer surface with a plating layer providing at least 97 wt. % tin. The tin of the plating layer provides alpha and beta phases of tin in an alpha/beta phase ratio of less than 10%.
