Thrust Needle Roller Bearing RAX730 30x38X22.2mm bearings Combined radial axial 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.
If you want to know more details, please feel free to contact us.
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

Feature
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.
