INA drawn cup needle roller bearings with open ends and with closed end are complete units comprising thin-walled, drawn cup outer rings and needle roller and cage assemblies. Drawn cup needle roller bearings are also available in a full complement design. The majority of the bearings are of a single row design.
INA drawn cup needle roller bearings are available in open and sealed designs. Open designs correspond to DIN 618-1/ISO 3 245.
In order to support axial forces, the bearings can also be combined with axial needle roller bearings AXW.
INA drawn cup needle roller bearings
Particularly low cross-section height
Due to the thin-walled outer cup and the design without an inner ring, INA drawn cup needle roller bearings have extremely small radial dimensions. They have high load carrying capacity, are suitable for high speeds and are particularly easy to fit. If axial means of location such as shoulders, snap rings etc. are not used, the housing bore can be produced easily and particularly economically.
Double row designs have a lubrication hole and the suffix ZW.
INA drawn cup needle roller bearings require a hardened and ground bearing raceway on the shaft. If the shaft cannot be used as a raceway, they can be combined with inner rings IR or LR.
