In contrast to drawn cup needle roller bearings with open ends, the bearings are closed at one end
Drawn cup needle roller bearings of this design are closed at one end. They are thus suitable for closing off the shaft ends of bearing positions. This gives protection against injury by rotating shafts and protects the bearings against contamination and moisture. Depending on the size, the base is either smooth or lock-beaded (stiffened). The profiled base can also support small axial guidance forces. Drawn cup needle roller bearings with closed end are available in open and sealed versions.
