Drawn cup needle roller bearings with closed end

Needle roller bearings are fitted with a thin-walled outer ring in a similar manner to needle bushes. They can also withstand high radial forces at minimum space requirements They are mainly used where only very little installation space is available.
Since cup needle roller bearings are enclosed on one side they are suitable for forming the end of bearing groups at shaft ends. The bearing is protected against dirt and moisture thanks to the floor (in other words the enclosed side) and can even withstand low axial guidance forces. Since this type of bearing is fitted with an outer ring, the housing borehole does not have to be designed as a raceway.
