<p>PROBLEM TO BE SOLVED: To provide a roller bearing capable of smoothing relative rotation movement of an outer ring and an inner ring by restraining high temperature of a roller during usage.SOLUTION: The roller bearing comprises: an outer ring 1 whose rolling face is formed in a circumferential direction of an inner periphery; an inner ring 2 whose rolling face 21 opposed to the rolling face 11 of the outer ring 1 is formed along an outer periphery; and multiple rollers 3 aligned on a roller rolling path 30 on which the rolling face 11 of the outer ring 1 and the rolling face 21 of the inner ring 2 are formed opposite to each other, and whose autorotation shafts are inclined to a rotation shaft of the outer ring or the inner ring 2. The outer ring 1 or the inner ring 2 has cooling flow passages 5a, 5b penetrating in the circumferential direction and formed hollow. At least one of the outer ring 1 and the inner ring 2 is formed as annularly by bending one or more linear members having the cooling flow passages 5a, 5b along the longitudinal direction jointing the end surfaces of the linear members.</p> |
