The present invention relates to an apparatus for testing a bearing, as well as systems including such an apparatus. In one instance, the apparatus allows for torsional losses of a bearing to be determined in a highly sensitive manner. Results can be determined in a controlled environment, as the system can include an environmental enclosure to encapsulate the testing apparatus.
