The maximum admissible flatness deviations are listed in the table as reference values.

Regarding the slope of the machined contact area the table values refer to 100 mm contact width.



Table 8:
Tolerated out-of-flatness including slope "P" of the machined support surface.

For special applications such as precision bearings with a high running accuracy and low bearing play, the values in Table 8 may not be used.

If the admissible values are exceeded, consultation should take place with Rothe Erde.

*) For normal bearing type 13 and normal bearing type 21 double values are certified.
