Claim:
A cylindrical roller bearing, comprising an inner ring having a raceway on an outer periphery thereof, an outer ring having a raceway on an inner periphery thereof, and a plurality of cylindrical rollers rotatably arranged between the raceway of the inner ring and the raceway of the outer ring, at least one of the inner ring and the outer ring being provided with collars respectively on both sides of its raceway, and at least one of the collars being provided with a recess at a corner where the raceway intersects a collar surface, wherein a critical skew angle θ T , that is a maximum skew angle at which a boundary between an end face and a chamfer of the cylindrical roller makes contact with a boundary between the collar surface and the recess, is restricted within a range of “θ T ≦14 minutes”; and a maximum skew angle θ MAX , at which both ends of a cylindrical roller respectively make contact with the collars on both sides, is restricted within a range of “20 minutes≦θ MAX ≦37 minutes”.
