The invention relates to a method for monitoring the function of a machine element lubricated by a lubricant. The method includes receiving measured values concerning the lubricant, determining a current chemical composition of the lubricant on the basis of the measured values, comparing the current chemical composition with chemical compositions known in advance, which are stored in a database, wherein function failure tendency values for the use of lubricants having the chemical compositions known in advance in connection with machine elements composed of materials known in advance are stored in the database, identifying a function failure tendency value on the basis of the comparison step, and outputting the function failure tendency value.

Method and system for monitoring the function of a lubricated machine element

A method for operating a bearing arrangement () including at least one rolling bearing (). The method provides for applying a positive electric potential to a bearing part () of the rolling bearing (), another part () of the bearing arrangement () being connected as a cathode, and a current flowing between the bearing part () and the cathode () is limited.

Method for operating a bearing arrangement

A roller bearing device () and to a method for operation thereof, including a roller bearing () having roller contacts () in contact with a medium and lubricated by the liquid medium (). In order to improve the lubrication and load capacity of such a medium-lubricated roller bearing () while simultaneously improving the biologically compatible behavior, a biologically neutral additive material () that thickens the medium is held available in a holding device () and metered to the roller contacts () on demand.
