HK Series Drawn Cup Needle Roller Bearing 

Feature of Needle roller bearing :

Needle Roller Bearings (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.
