DESCRIPTION:
1. SKF needle roller bearings with machined rings are made of carbon chromium bearing steel. Relative to their low sectional height, they have a high load carrying capacity. SKF supplies needle roller bearings with machined rings with or without flanges on the outer ring, in a wide range of series and sizes. SKF also supplies these bearings with or without an inner ring.
2. 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.
