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
Drawn cup needle roller bearings with open ends and drawn cup needle roller bearings with closed end are available in an unsealed design in accordance with DIN 618-1/ISO 3 245 and a sealed design in accordance with DIN 618-2.
Under normal operating conditions, the lip seals give protection against contamination, spray water and the loss of lubricant.
