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.
