<P>PROBLEM TO BE SOLVED: To provide a cylindrical roller bearing having construction for reducing significant wear or friction due to skewing without increasing manufacturing cost. <P>SOLUTION: Inside faces 12, 12 of collars 8a, 8a are substantially perpendicular to the center axes of an inner ring 3a and an outer ring 5. ä0.5d+(b<SP>2</SP>/4s)}≤h<d is established, where h is the height of each of the collars 8a, 8a from an inner ring raceway, d is the outer diameter of each of cylindrical rollers 6, b is the contact length of the end face of the cylindrical roller 6 when abutting on the inside face of the collar 8a, and s is the outer diameter of the collar 8a. As a result, the maximum skewing angle is reduced when each of the cylindrical rollers 6 is skewed and a slide contact portion between each of the end faces of the cylindrical rollers 6 and each of the inside faces 12, 12 of the collars 8a, 8a is located within each of the inside faces of the collars 8a, 8a at the side of the base end beyond the front edge of the collar. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
