A device for testing greases of the type in which a bearing is run in the lubricant and the frictional moment and operating temperatures measured, comprises anti-friction bearings 1, 2 subject to axial load to eliminate play. The bearings support a shaft 3 driven by a motor 4 and one, 2, is supported in a fixed housing 5 which may incorporate heating or cooling means, while the other, 1, is carried on an element 6 slidable in the housing 5 and subject to an axial load.
