The rugged solution for shafts with centering thread
Flange adapter shafts facilitate the convenient, simple and stable attachment of hollow shaft encoders to large shafts with a centering thread. Thanks to three integrated ball thrust screws it is possible to easily and precisely adjust the adapter shafts. Screw-in type adapter shafts are ideally suitable for retrofitting and replacement solutions. If required, they are also available as certified safety components with fault exclusion to DIN EN ISO 13849-2 (PL e) and as an isolated version to shield against shaft currents.
