The advanced principle of the needle roller bearing in the outer ring is the large volume of the grease in the body.


One end of the stamped outer ring needle roller bearing seal type bearing is sealed. It can be used under long-term lubrication conditions and under high load conditions due to high temperature lubrication. Needle bearings can only withstand radial forces in actual operation.

And because this bearing does not limit the axial displacement, even if there is an axial force will not be affected, but not too frequent, otherwise it will have a greater impact on the use and life of the bearing.
