PROBLEM TO BE SOLVED: To provide a cylindrical roller bearing into which an inner ring, an outer ring and a cylindrical roller can be easily assembled without disassembling them even in a structure that they can separate from each other.SOLUTION: A cylindrical roller bearing 10 includes: an outer ring 20 having a pair of flange parts 22 on both sides of an outer ring raceway surface 21; an inner ring 30 having no flange part at least at one end part in an axial direction; and a plurality of cylindrical rollers 40. Also, the cylindrical roller bearing 10 includes a disassembly prevention rubber 50 mounted between the outer ring 20 and the inner ring 30, and holding a radial relative position between the outer ring 20 and the inner ring 30 with elastic force.SELECTED DRAWING: Figure 1 |
