Rolling bearing device and roll apparatus for continuous casting installation

A rolling bearing device, comprising:

• an inner ring, comprising an outer circumference formed with an inner raceway surface;
• an outer ring, comprising:
• an inner circumference, formed with an outer raceway surface;
• an axial outer side face, formed with a first raceway surface;
• and
• an outer circumference, formed with an outer sliding surface having a convex-arcuate axial cross section;
• a plurality of cylindrical rollers, rollably disposed between the inner raceway surface and the outer raceway surface;
• an aligning housing ring, comprising an inner circumference formed with an aligning sliding surface having a concave-arcuate axial cross section and being in slidable contact with the outer sliding surface;
• a side raceway ring, disposed in an axial outer side of the outer ring and formed with a second raceway surface opposing the first raceway surface;
• and
• a plurality of tapered rollers, disposed between the first raceway surface and the second raceway surface, wherein:
• 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 of the aligning sliding surface.
