Bearing data

Dimension
standards
d, D: ISO 15

D ≤ 47 mm → diameter series 0

D ≥ 55 mm → diameter series 9

Tolerances

For additional
information
Tolerances
  • Normal for the inner ring and the outer ring with sphered outside surface
  • C of the external drawn sheet steel sleeve: ± 0,5 mm
  • Fw: F6 (table 1)
    Values are valid for unmounted bearings and when rollers are in contact with the outer ring raceway.

Values: ISO 492 (table 2)

Operating clearanceBearings without an inner ring

Range of C2 to C3 if recommended tolerances (table 3) applied

Internal clearanceNormal (bearings with an inner ring)

Check availability of C2, C3 or C4 clearance classes


Values: ISO 5753-1 (table 4)
Values are valid for unmounted bearings under zero measuring load.
Permissible misalignment≤ 3° static misalignment

No dynamic misalignment


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