FIELD: mechanical engineering. SUBSTANCE: method consists in feeding liquid lubricant from oil accumulating unit of transportation roller 6 to friction zone of unit 3 through capillator 7 and separator-centrifugal distributor 8 and holding it there by means of sealing members 4. Capillator is immovably connected with oil accumulator and is movably connected with separator-centrifugal distributor of bearing unit which is provided with holes 9 on end surface 10 in area of movable contact 11 with capillator. Number of holes is no less than 24; holes are made in three rows at angle of 25 to 35 deg relative to axis of rotation of bearing unit. EFFECT: increased service life of bearing unit; low cost of servicing and repair jobs. 1 dwg
