The apparatus comprises a spindle 1 on which the sleeve 2 and the fixed nut 3. counterface 4 - "fixed shaft" is set and fixed on the flange of the loading carriage 5 traction machine. Through the interior of the fixed shaft 4 to the fitting 6 of the container situated above the level, is supplied the lubricant (oil). Protective cover 7 prevents splashing lubricant (oil), which is given via the connection 8 to the empty container disposed below the level. The utility model is aimed at expanding technological possibilities of friction machine 2070 STS-1, and to obtain reliable results of tribological tests of bearings and lubricants for the purpose of sound application of them in the real nodes of friction energy saturated technique. 1 yl.
