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. These bearings allow the design of particularly compact and easy to fit bearing arrangements with high radial load carrying capacity. In order to support axial forces, they can also be combined with axial needle roller bearings AXW.

The majority of the bearings are of a single row design and do not have a lubrication hole. Double row designs have a lubrication hole and the suffix ZW.

For particular applications, drawn cup needle roller bearings with open ends are also available in a full complement design.

Drawn cup needle roller bearings require a hardened and ground bearing raceway on the shaft. If the shaft cannot be used as a raceway, the bearings can be combined with inner rings IR or LR.
