Railway Bearing for Freight Car RNA 6909 needle roller bearingKOYO INA RNA6909 52x68x40 mm
Needle roller bearing :
Needle Roller Bearing (needle bearing) is a cylindrical roller with
roller bearings, relative to its diameter, roller both thin and
long. This is called needle roller. Despite having a smaller
cross-section, has a higher load bearing capacity, equipped with a
thin and long needle bearing roller (roller diameter D≤5mm, L /
D≥2.5, L is the length of the roller), so radial structure is
compact, its diameter size and load capacity and other types of
bearings, minimum diameter, especially for radial dimensions
limited support structure.
