PROBLEM TO BE SOLVED: To improve productivity of a machine tool including a rolling bearing 1 by shortening or eliminating break-in after injecting grease in the rolling bearing 1, and supplying a sufficient quantity of lubricant during load operation. SOLUTION: Filling work of rotating an inner ring 2 after injecting grease little by little in an annular space 9 existing between the inner ring 2 and an outer ring 3, is repeatedly performed. With this work, the grease is stuck over the whole of the parts coming in rolling contact following the rotation of the inner ring 2, out of the rolling surfaces of balls 7, 7 and an inner ring raceway track 4 and an outer ring raceway track 5 in a state before the rolling bearing 1 is built in a rotation support part of machinery to start operation.
