Abstract: The device is assigned to the sphere for measurement of surface wear and applied in the technology of the machinery industry. The purpose of the invention is to increase the accuracy of assessment of the surface wear characteristics by expanding the test conditions of the analysed contact and continuously observing the state of the friction pair in the course of the test. The device is comprised of a bottom holder (1) whereto a bottom workpiece (2) is secured, a spring displacing in the Y-direction (3), a multilayer piezo element (4) moving in the Y-direction, a housing (5), a multilayer piezo element (6) moving in the X-direction, a multilayer piezo element (7) moving in the Z-direction, a spring displacing in the X-direction (8), a top holder (9), a linear air bearing housing (10), a spherical upper workpiece (11), a linear air bearing shaft (12), a sensor (13), a moving support of the flat air bearing (14), a flat air bearing housing (15), a high frequency generator (16), an amplifier (17), a control board (18), an electrical signal filter (19), a computer (20), a sensor signal amplifier (21), a multilayer piezo element (22) moving in the X-direction, a multilayer piezo element (23) moving in the Y-direction and a flat air bearing (24)
