SKF spherical roller bearings are manufactured as standard to
Normal tolerances.
SKF Explorer spherical roller bearings up to and including 300 mm
bore diameter are, however,
produced to higher precision than the ISO Normal tolerances.
For example
| –
|
the
width tolerance is
considerable tighter than the ISO Normal tolerance, |
| –
|
the running accuracy is to tolerance class
P5 as standard. |
For larger bearing arrangements where running accuracy is a
key operational parameter, SKF spherical roller bearings
with P5 running accuracy are also available. These bearings
are identified by the suffix C08. Their availability should
be checked.
The tolerance for the bore and the outside diameter of SKF
Explorer spherical roller bearings for vibratory
applications have been reduced from Normal to
P5 and
P6 respectively.
The values of the tolerances are in accordance with ISO 492:2002.
