Drawn cup needle roller bearings with open ends
Drawn cup needle roller bearings with open ends and with closed end are needle roller bearings with a very small radial section height. They comprise thin-walled, drawn cup outer rings and needle roller and cage assemblies which together form a complete unit. The outer rings adapt themselves to the dimensional and geometrical accuracy of the housing bore.
In contrast to bearings produced by machining methods, the dimensional and geometrical accuracy of drawn cup needle roller bearings with open ends and with closed end is not based on ISO492, but on DIN618. If the shaft cannot be produced as a raceway, the bearings can be combined with inner rings.
