Abstract
A cylindrical roller bearing includes at least one outer ring with a raceway, an inner ring with a raceway, and a plurality of cylindrical roller elements rollable along the raceways of the inner ring and the outer ring. The raceway of the inner ring has an at least partly crowned profile, the crowned profile having a crowning radius R and is formed such that: 25 L2/D<R<55 L2/D, in which L is the length of each one of the cylindrical roller elements and D is the diameter of each one of the cylindrical roller elements.

A cylindrical roller bearing comprising:
- at least one outer ring with a raceway,
- an inner ring with a raceway,
- a plurality of cylindrical roller elements rollable along the raceways of the inner ring and the outer ring, and
- a roller guided cage arranged radially inwardly of a pitch diameter of the cylindrical roller elements and spaced radially outwardly from the inner ring, the cage including two side rings and a plurality of cage bars connecting the side rings so as to form pockets, the cylindrical roller elements being accommodated within the pockets,
- wherein the raceway of the inner ring has an at least partly crowned profile, the crowned profile having a crowning radius R and is formed such that:
- 25L2/D<R<55L2/D,
- wherein L is the length of each one of the cylindrical roller elements and D is the diameter of each one of the cylindrical roller elements;
- and
- wherein the inner ring raceway formed with the crowned profile having the crowning radius R and the roller guided cage being spaced radially outwardly from the inner ring enables an angular misalignment (β) in the full range of +/−1° and an axial displacement in the full range of 0% to 25% of an axial length of the inner ring.
