Bearing data

Dimension standards

Boundary dimensions: ISO 15

Tolerances

For additional information → Tolerances

Normal dimensional tolerance

P6 geometrical tolerance


Values: ISO 492 (table 1, table 2)

Radial internal clearance

For additional information → Selecting internal clearance or preload

Normal, C3

Check availability of other clearance classes


Values: ISO 5753-1 (table 3)


Values are valid for unmounted bearings under zero measuring load.

Permissible misalignment

≈ 3 minutes of arc


Misalignment increases bearing noise and reduces bearing service life, and when it exceeds the guideline value these effects become particularly noticeable.

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.
