FIELD: mechanical engineering; metal working; manufacture of bearings and finishing of bearing races of radial roller bearings. SUBSTANCE: bar holder 3 with abrasive bar 4 is located in housing 1 between two diaphragms 13 with supports 5. Housing 1 is installed for rocking relative to axle 2 with larger amplitude and variable speed under action of cam 10 whose shape defines movement of abrasive bar 4 along roller path of race 12.
