Bearing data

Dimension standards

Not standardized

Bore and outside diameter for many bearings: diameter series 9 or 0 (ISO 15)


For additional information → Tolerances

  • P6 dimensional tolerances
  • P5 geometrical tolerances

Values: ISO 492 (table 1, table 2 and table 3)

Radial internal clearance

For additional information → Internal clearance

C3 or C4

Except for bearings with a helical groove in the inner ring(s) bore (feature G in the Design variant/feature → product table): C2

Values: ISO 5753-1

Values are valid for unmounted bearings under zero measuring load.

Permissible misalignment

Misalignment increases bearing noise and reduces bearing service life.

For bearing arrangements where misalignment cannot be avoided, contact the SKF application engineering service.

Permissible axial displacement (fig. 1)

smax → product table

Bearings having no flange, or only one integral flange on either the inner or outer ring(s), can accommodate axial displacement within certain limits. Displacement of the shaft relative to the housing occurs within these bearings. As a result, there is virtually no increase in friction.
