Abstract
The surface roughness of the rolling surface 2 of the roller 1 along both the axial and circumferential direction is 0.06 .mu.m RA or less, while the surface roughness of the opposing inner ring raceway 4 is 0.08 to 0.15 .mu.m Ra along the axial direction, and 0.04 or less along the circumferential direction, whereby the heat generated by the roller bearing is kept to a minimum, and the danger of burning of the roller bearing is reduced.
