Kind Code:
A1
Abstract:
Provided is a roller bearing capable of improving load rating and rigidity. Disclosed is a roller bearing (5) wherein: a plurality of rollers (3) are arranged between track grooves formed respectively in an inner race (1) and an outer race (2), each track groove having a V-shape in a cross-sectional view; and a spacer (4) is arranged between adjacent rollers (3). The thickness of each spacer (4) defining the interval between the adjacent rollers (3) is made thin so that the thickness is at most 20% of the roller diameter. To prevent the spacer (4) from collapsing, the diagonal dimension of the spacer (4) in a side view is set so as to be greater than the roller diameter.
