Mounting tolerances

Observe the following points.

  • The table values for radial misalignment and angular misalignment apply to common mechanical couplings, such as elastic claw couplings or couplings with a steel lamella package.
  • The values listed below result from the consideration of the entire drive train and therefore differ from the tolerance values of the coupling manufacturers.
  • Drive speeds greater than 1500 min-1 in conjunction with coupling diameters greater than 400 mm require a case-by-case test and approval.
  • All tooth and barrel couplings must be set and aligned according to the respective manufacturer's operating instructions.
  • The setting and alignment tolerances for special couplings must be checked and agreed on in individual cases.

Observe the following information.

The installation tolerances stated in the table apply to flexible couplings.
