ROFLEX® failsafe shaft couplings

Torsionally flexible, failsafe shaft couplings

A particular feature of the torsionally flexible and failsafe ROFLEX® shaft coupling is its short design resp. short DBSE [Distance Between  Shaft Ends]. Short shaft distance dimensions allow for space-saving power packs.

A new option of the proven coupling according to DIN 740 is its combination with a split cam section (ROFLEX SH) which is manufactured via fracture separation, also called cracking. In times of availability, ease of servicing, compact designing and operational safety the properties to be short and easy to service are a vital benefit that every operator appreciates. 

It goes without saying that the ROFLEX offsets any kind of shaft displacement (axial, radial, angular) reliably while damping shocks and reducing torsional vibrations. 

The ROFLEX is approved for use in potentially explosive atmospheres. This is confirmed by the ATEX approval that applies for the European region and the EAC declaration which is intended for the Eurasian region. The ATEX type examination certificate and EAC certificate are specified in the menu item "Service".
