Abstract

A bearing including a first and a second bearing element that are movable relative to one another, a lubricant arranged between the first and the second bearing element for reducing the friction between the first and the second bearing element, at least one transmitter for exciting acoustic waves in the first or the second bearing element, the transmitter being arranged on the first or the second bearing element; at least one receiver for receiving acoustic waves evoked by the transmitter, the receiver being arranged on the first or the second bearing element, wherein information related to properties of the lubricant can be determined using a signal generated by the receiver upon receipt of acoustic waves evoked by the transmitter. The invention is also related to a method for determining properties of a lubricant in a bearing.
