<p>PROBLEM TO BE SOLVED: To provide a cylindrical roller bearing which suppresses revolution slide of a roller by giving the minimum required axial pre-load properly without relying on trial and error. SOLUTION: Axial load Fa having the following relationship is given to a roller 3 of a radial cylindrical roller bearing through a collar 5 to suppress slide between the roller 3 and races (outer ring 1, inner ring 2). Fc.Z/Fa<= 0.70 in the case of pre-load between an inner ring collar and an outer ring collar, and Fc.Z/Fa<=1.0 in the case of pre-load between the inner ring collar or the outer ring collar, wherein Fc is revolution centrifugal force of the roller, m is mass of the roller, dm is diameter of roller pitch circle, and Wt is roller revolution angle speed, and Fc has the relationship, Fc=m.1/2.dm.Wt<2> . Z is the number of rollers.</p> |
