This type of roller is called a needle roller. Although the section is small, the bearing still has a high load capacity, and the needle roller bearing is equipped with slender rollers (roller diameter D≤5mm, L/D≥2.5, L is the length of the roller), so the radial structure It is compact, with the same inner diameter size and load capacity as other types of bearings, and the smallest outer diameter, especially suitable for support structures with limited radial installation size.
