Tolerances
ISO 3245, as far as standardized
  • Fw ≈ within F8 (table 1)
    Measuring of Fw:
    • bearing must be pressed into a thick-walled ring gauge, bore diameter listed in table 1
    • check deviation of Fw with measuring mandrel

  • C: 0/–0,3 mm
Dimensional tolerances can be checked only if bearings are mounted.
Operating clearanceRange of C2 to C3 if recommended tolerances (table 2) applied

Permissible misalignment

≈ 1 minute of arc


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