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.
