Bearing data

Dimension standards

Boundary dimensions: ISO 15

Drawing number bearings
Bore and outside diameter for most of the bearings: diameter series 0 (ISO 15)

Tolerances

For additional information → Tolerances

Normal

Drawing number bearings
  • P6 dimensional tolerances
  • P5 geometrical tolerances

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

Radial internal clearance

For additional information → Selecting internal clearance or preload

Normal

Check availability of other clearance classes

Drawing number bearings
Range of C2 to C4 as identified in the Design variant/feature (→ product table)

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 (e.g. in rolling mill straightening machines), 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, can accommodate axial displacement. Displacement of the shaft relative to the housing occurs within these bearings. As a result, there is virtually no increase in friction.
