Drawn cup needle roller bearing open end HK0306-TV-A INA

Description

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. The outer rings adapt themselves to the dimensional and geometrical accuracy of the housing bore. In contrast to bearings produced by machining methods, the dimensional and geometrical accuracy of drawn cup needle roller bearings with open ends and with closed end is not based on ISO492, but on DIN618. If the shaft cannot be produced as a raceway, the bearings can be combined with inner rings. Drawn cup needle roller bearings are available either with both ends open or with one end closed. In addition to the design with a cage, drawn cup needle roller bearings with open ends are also available with a full complement needle roller set. These series have the maximum number of needle rollers and therefore offer extremely high load carrying capacity within a very small design envelope. Their use at high speeds is restricted. If axial locating elements such as shoulders and snap rings are not used, the housing bore can be produced easily and particularly economically. This also gives simpler mounting and dismounting of the bearings. In order to support axial forces, the bearings can be combined with axial bearings.
