description PROBLEM TO BE SOLVED: To provide a method for easily and consistently manufacturing a polymer lubricant sealed bearing having a structure that polymer lubricant sealed between inner and outer rings of a double row self-aligning roller bearing is divided between two rows of rolling elements, and the divided lubricant can be rotated independently from each other. SOLUTION: After assembling the double row self-aligning roller bearing, ring-shaped spacers 21a and 21b for division are inserted between two rows of the rolling elements 3a and 3b utilizing the fact that the outer ring 2 of this self-aligning roller bearing can be turned in the direction orthogonal to the axis of the bearing with respect to an assembly 10 comprising an inner ring 1, the rolling element 3 and holders 4a and 4b. Raw polymer lubricant is poured and solidified in each area of an annular space between the inner ring 1 and the outer ring 2 divided into two areas in the axial direction by the spacers 21a and 21b for division, and then, the spacers 21a and 21b for division are removed. The polymer lubricant sealed bearing with a pair of reliably separated polymer lubricant 5a and 5b sealed therein can be easily obtained thereby.
