摘要： PROBLEM TO BE SOLVED: To provide a self-aligning roller bearing with a cage constructed to hardly damage inner ring raceways 6, 6 during work for assembling spherical rollers 3, 3 while preventing the come-off of the spherical rollers 3, 3 from pockets 9, 9 of the cage 4a.
SOLUTION: The length of each of columnar portions 8a, 8a of the cage 4a is larger than 1/2 of the length of each of the spherical rollers 3, 3. A circumferential space between both front edges of the columnar portions 8a, 8a neighboring each other in the circumferential direction is smaller than the maximum diameter of each of the spherical rollers 3, 3. This construction prevents the come-off of the spherical rollers 3, 3 from the pockets 9, 9. Besides, both entry grooves 12a, 12a are formed ranging to the base ends of outward collar portions 10, 10. This construction avoids strong friction between the front end outer peripheral edge of each of the spherical rollers 3, 3 and each of the inner ring raceways 6, 6 during assembling work to prevent damage to each of the inner ring raceways 6, 6.
