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.

The RAX730 needle roller-thrust needle roller bearing is a combination of a punched cup needle roller bearing and a thrust needle roller bearing.This combination bearing is stamped and can save a lot of space. Can withstand radial light loads and axial heavy loads
RAX730 needle roller bearing
Cage and its material
F1 carbon steel
carburizing bearing steel (hardened)
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.
