<p>A tapered roller thrust bearing is disposed in each of both sides in an axial direction of a cylindrical roller bearing with aligning housing ring which is provided with an inner ring, an outer ring, cylindrical rollers and an aligning housing ring. The tapered roller thrust bearing is constituted by disposing tapered rollers between a first raceway surface which is an outer side face in the axial direction of the outer ring and a second raceway surface of a side raceway ring disposed in an outer side in the axial direction of the outer ring. An intersection of lines extended from generatrices of each of the tapered rollers which are in contact with the first raceway surface and the second raceway surface, and an intersection of lines extended from the first raceway surface and the second raceway surface are disposed on a curvature center O of the aligning sliding surface.</p> |
