| Keterangan: | IKO inner Rings are heat-treated and finished by
grinding to a high degree of accuracy. In the case of
needle roller bearings, normally, the shafts are heattreated
and finished by grinding, and used as the
raceway surfaces. However, when it is impossible to
make shaft surfaces according to the specified surface
hardness or surface roughness, inner rings are
used.
Inner rings include those for Shell Type Needle Roller
Bearings and those for general use and are available
in a variety of dimensions. When shafts move axially
or seals are used adjacent to bearings, wide inner
rings can be selected.
Inner rings can also be used economically as bushings
without requiring any additional machining. |
