Product overview Product characteristics Elastomer ring The elastomer ring transmits torques without backlash and dampens vibrations. This determines the properties of a complete coupling or a complete drivetrain. Freedom from backlash The compressive prestressing of the elastomer ring ensures the freedom of the coupling from backlash.
Product overview Intended use The elastomer couplings from the AX2090-ECxx series may be op- erated only for the intended activities defined in this documentation, taking into account the prescribed environmental conditions. The components are to be installed in electrical systems or ma- chines and only put into operation as integrated components of the system or machine.
The elastomer couplings could be damaged if you do not adhere to the permissible temperatures and specifications for operation and environment. Beckhoff products are designed for operation under certain environ- mental conditions, which vary according to the product. The follow- ing specifications must be observed for operation and environment in order to achieve the optimum service life of the products.

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 off- set are given in the "Technical data", [Page 16].
Technical description Installation Check the spacing distance Check the spacing distance specified in the Technical data so that the elastomer ring is axially movable. The elastomer coupling can be damaged and fail if you do not ad- here to the permissible spacing distance. With intermediate flange If you install the elastomer coupling in an intermediate flange, be sure to make the centering fits and plane parallelisms of machine...
The use of unsuitable lubricants can lead to incompatibility with the elastomer ring and impair the functionality. Facilitated assembly The bores in the coupling hub have an H7 fit. Beckhoff recom- mends play of 0.1 – 0.5 mm between the coupling hub and the shaft.
Adhere to the concentricity and axial run-out accuracies and do not clamp to the hub bridges. For customer-specific special solutions and changes to the coupling hubs, contact our Applications Department. Beckhoff GmbH & Co. KG accepts no liability for unapproved, unauthorized conversions and modifications of the components.
Maintenance and cleaning WARNING Shut down and secure the machine or plant Make sure that the machine or plant is shut down and secured against accidental start-up. Failure to observe may result in components moving in the ma- chine or plant. Rotating or moving components can lead to seri- ous injuries.
The trans- 9.2.1 port costs are borne by the sender. Send the used devices with the note "For disposal" to: Beckhoff Automation GmbH & Co. KG Gebäude „Service“ Stahlstraße 31 D-33415 Verl In addition, you have the option to contact a local certified specialist company for the disposal of used electrical and electronic appli- ances.
