NA 69 Series NA6904

NA69: Double Row Machined-Ring Needle Roller Bearing, heavy-duty needle roller bearings.

Needle roller bearings of the series NA69 series NA6904 are wider and heavier than needle roller bearings of the series NA49 and can thus support considerably higher radial loads. Needle roller bearings with an inner ring are used for applications where the shaft cannot be hardened and ground. The permissible axial displacement of the shaft relative to the housing is limited for bearings with an inner ring. If the permissible axial displacement provided by a standard inner ring is insufficient, it is possible to use an extended inner ring.
