Eccentricity and concentricity
According to the DIN 42955 standard, the maximum deviations allowed
for rotating eccentricity on the shafts are given in table
T- 1/6 .
The table T- 1/7 shows the tolerance values admitted for concentricity of
the coupling diameter and for axial eccentricity of the supporting side of
the flange with respect to the machine axis.
Noise emission. Acoustic pressure level
Meets the DIN 45635 standard.
T- 1/6 Radial eccentricity tolerances.
