    摘要: The present invention relates to a system configured to monitor a condition of a rotating system comprising a main bearing, the monitoring arrangement having a first measurement device configured to be arranged at a first location in proximity of the main bearing for determining a first measurement indicative of a current flow at the first location, and a control unit connected to the measurement device. The control unit is further configured to form a first parameter based on the first measurement, match the first parameter with a plurality of predetermined current flow profiles, each of the plurality of predetermined current flow profiles being indicative of a condition of the rotating system, determine, if a matching current flow profile is found, a relevance level for the corresponding condition, and provide an indication of an alarm if the relevance level is above a predetermined threshold.

    摘要: An annular guide ring for controlling the position of at least one of rolling elements and a bearing cage in relation to an inner ring of a rolling bearing. The guide ring comprises a base portion, a first side portion extending in a radial direction from a first axial end portion of the base portion, and a second side portion extending in a radial direction from a second axial end portion of the base portion, wherein the first side portion and the second side portion are integrally formed with the base portion of a one-piece sheet material. Also described is a method for manufacturing the guide ring for the rolling bearing.
