  • 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 accuracy can be checked only if bearings are mounted.
Operating clearanceRange of C2 to C3 if recommended tolerances (table 2) applied
Misalignment≈ 1 minute of arc

The permissible angular misalignment between the shaft and the housing depends on the size and internal design of the bearing, the radial internal clearance in operation and the forces and moments acting on the bearing. As a result, only an approximate value is listed here. Any misalignment increases bearing noise and reduces bearing service life.
