摘要： A rolling bearing cage includes at least one cage side ring and a plurality of cage bars extending from the cage side ring so as to form a plurality of pockets, each pocket being defined between a separate pair of adjacent bars, for receiving rolling bodies of the rolling bearing. A cage breakage detection unit includes at least one conductive track and a module for wireless cage breakage monitoring. The cage has at least one recess, in which at least a prefabricated part of the cage breakage detection unit is inserted and fixed.

摘要： Method for detecting at least one critical defect in a ceramic rolling element providing the steps of capturing a plurality of two-dimensional digital radiographic images of the rolling element; digitally filtering each radiographic image; delineating, on the basis of the filtered image, at least one region liable to comprise the critical defect; constructing stereoscopically a virtual model of the rolling element having the region; comparing the dimensions of the delineated region with a plurality of predetermined threshold values, and, when the dimensions are greater than the threshold values, generating an alarm signal.

摘要： An assembly providing a bearing, a lubricant and a contamination sensor for determining a level of contamination in the lubricant. The sensor includes an EM wave generator for generating an EM signal, and an EM sensing element arranged in contact with the lubricant. The EM sensing element receives the generated EM signal and transmits an output signal whose properties are responsive to real and imaginary parts of a complex relative permittivity of the lubricant. The output signal is received by an EM measuring device that measures first and second parameters of the output signal, which are respectively representative of the real and imaginary parts of the complex relative permittivity. The EM measuring device determines a level of water contamination in the lubricant, based on the measured first parameter alone and determines a level of metal particle contamination in the grease, based on the measured first and second parameters.
