Description

INA Drawn cup needle roller bearings with open ends and with closed ends 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.

Due to the thin-walled outer cup and the design without an inner ring, 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.

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.
