SKF single row deep groove ball bearings are manufactured as
standard to
Normal tolerances.
SKF Explorer single row deep groove ball bearings are
produced to higher precision than the ISO Normal tolerances.
The dimensional accuracy corresponds to
P6
tolerances, expect the width tolerance, which is
considerably tighter and reduced to
| – |
0/–60 μm for bearings with outside diameter up to 110 mm
|
| – |
0/–100 μm for larger bearings. |
The running accuracy depend on the bearing size and
corresponds to
| – |
P5 tolerances for
bearings up to a 52 mm outside diameter |
| – |
P6 tolerances for
bearings above 52 mm up to 110 mm outside diameter |
| – |
Normal tolerances for
larger bearings. |
For bearing arrangements where accuracy is a key operational
factor, some SKF single row deep groove ball bearings are
also available with accuracy completely to P6 or P5
tolerance class specifications. The availability of these
bearings should always be checked before ordering.
The tolerances for classes Normal, P6 and P5 are in
accordance with ISO 492:2002.
