摘要： PROBLEM TO BE SOLVED: To provide a self-aligning roller whose productivity is further enhanced while the service life of a bearing is assured. SOLUTION: An outer ring 20 is axially divided into two outer ring members 21 and 22, which are formed with respective raceway surfaces 21e and 22a for a roller 30, so that even if a guide ring 40 has a completely circular ring shape, for example, it can be easily mounted in place when sandwiched between the two outer ring members 21 and 22. Mounting the guide ring 40 in a manner such that it is sandwiched between the two outer ring members 21 and 22 eliminates the need for removing the roller 30 beforehand and enhances working efficiency even when a cage 50 and the roller 30 are integrally assembled.

摘要： PROBLEM TO BE SOLVED: To realize a structure capable of easily performing processing of an oil passage for taking lubricant to the inside of a bearing and supplying a sufficient amount of lubricant to an inner ring raceway 4 through the oil passage.
SOLUTION: A plurality of through-holes 18, 18 are formed to penetrate a small diameter side collar part 9b in the axial direction composing an inner ring 5b as oil passages for taking the lubricant to the inside of a tapered roller bearing 1b. By each of the through-holes 18, 18, a sufficient amount of the lubricant can be directly supplied to the inner ring raceway 4 regardless of centrifugal force acting on the lubricant. Further, scales adhered inside each of the through-holes 18, 18 can be easily removed because diameters of each through-hole 18 can be secured large, and accordingly, the problem can be solved.
