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.
