Shaft offset

The purpose of the elastomer couplings is to compensate the lateral, axial and angular shaft offsets.

Prolonged service life through precise alignment

The service life of the elastomer coupling will be prolonged by precise alignment. The load on the bearing is thereby reduced so that the running smoothness of the entire drivetrain is positively affected.
Beckhoff recommends alignment using a dial gauge if you use the elastomer coupling with very high speed drives.

The maximum permissible guide values for the different types of offset are given in the Technical data. Operationally-related influences such as thermal elongation can be compensated by adhering to the permissible guide values. The maximum permissible guide values must be reduced if several types of offset occur simultaneously. The sum of the actual offsets as a percentage of the maximum value may not exceed 100%.
