Bearing data


d, D: ISO 15:2011

D ≤ 47 mm → diameter series 0

D ≥ 55 mm → diameter series 9


For additional
(→ 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 in contact with the outer ring raceway.

Values: ISO 492:2014 (table 2)
Operating clearance

Bearings 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 5753-1:2009 (table 4)
Values are valid for unmounted bearings under zero measuring load.

≤ 3° static misalignment

No dynamic misalignment

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.
