摘要: In rollers used in a radial needle bearing, the circularity of crowning sections provided at opposite ends of each roller is 0.6 μm or smaller. This allows for reduction of sound (noise) produced when the radial needle bearing rotates by itself and can also allow for reduction of sound (noise) of a rotational machine when the radial needle bearing is installed and rotates therein.
