The rugged solution for shafts without centering thread

Flange adapter shafts facilitate the convenient, simple and stable attachment of hollow shaft encoders to large shafts without a centering thread. Depending on the on-site situation they are attached to the front face of the application shaft with external centering or internal centering; consequently, they are ideal as 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.

Technical Data

AttributeValue
Product usage

Mounting hollow shaft encoders to shaft with large diameter:

  • External centering customer shaft (flange-adapter shaft with internal centering)
  • Internal centering customer shaft (flange-adapter shaft with external centering)

Possible for all encoder installation positions (for example, shaft facing up/down).

Mounting type

Following inspection/agreement:

  • External centering customer shaft: Centering diameter approx. Ø 28-350 mm (encoder series 4/40/41)
  • Internal centering customer shaft: Centering diameter approx. Ø 30-290 mm (encoder series 4/40/41)
  • External/internal centering customer shaft: Centering diameter approx. Ø 50-200 mm (encoder series 5/6/60)
  • Custom design customer shaft possible up to centering diameter Ø 500 mm or as per customer preference
