PROBLEM TO BE SOLVED: To provide a self aligning roller bearing by which a possibility of excessive temperature increase can be prevented and reliability for a using condition under a high speed and a high load can be increased. SOLUTION: In an inner ring 1 of an self aligning roller bearing, two raceways tracks 1a are formed, while in the outer end part of each raceway track 1a, a fall out preventive flange 1b is formed respectively. In an outer ring 2, raceway tracks 2a respectively opposed to the raceway tracks 1a in the inner ring 1 are formed. Rollers 3 in two lines are arranged individually between the respective raceway tracks 1a in the inner ring 1 and the respective raceway tracks 2a in the outer ring 2, and the roller 3 in each line are held by means of an integrally constructed retainer 6. A clearance between the inner ring 1 and the outer ring 2, a clearance between each of the fall out preventive flanges 1b in the inner ring 1 and the outer end faces of the rollers 3 in each line, and a clearance between the inner end faces of the rollers 3 in each line and a guide ring 7 are respective filled with lubricant containing polymer 8.
