Abstract

A double-row roller bearing which can be used with low torque by suppressing increase in stirring resistance of lubricant while preventing skew of rollers surely and reducing generation of heat during use. The double-row roller bearing consists of an outer ring (1) having two outer rolling grooves (10) formed in the inner circumferential surface, an inner ring (2) having two inner rolling grooves (20) formed in the outer circumferential surface oppositely to the outer rolling grooves (10) of the outer ring (1), and a large number of rollers (3) arranged in the rolling path where the outer rolling grooves (10) and the inner rolling grooves (20) are formed oppositely to each other. The outer rolling grooves (10) and the inner rolling grooves (20) have a substantially V-shaped cross-section formed by permitting a rolling face (17) on which the roller (3) rolls to intersect the skew regulation surface (14) opposing the axial end face of the roller (3) through a minute gap. Furthermore, a pair of annular grooves (15a, 15b) are formed in the skew regulation surface (14) of the outer rolling groove (10) along the circumferential direction of the outer ring (1) while holding a part of the roller (3) opposing the axis of rotation of the same therebetween.
