Permitted shaft misalignment
The permitted shaft misalignment depends on the operating
speed. As the speed increases, lower shaft misalignment values
are permitted. The following table shows the correction factors
for different speeds. The maximum speed depending on the re-
spective coupling size and type must be observed!

The axial misalignment may occur dynamically at frequencies
up to 10 Hz. For fitting, the maximum gap dimension of
S2 max. = S2 +
Δ
S2 and the minimum gap dimension of
S2 min. = S2 -
