ROFLEX® N torsionally flexible, failsafe shaft coupling

Short and low-cost standard version

The torsionally flexible, failsafe shaft coupling ROFLEX N is a short, two-part shaft coupling according to DIN 740 for torsional vibration damping power transmission. The compact design of ROFLEX N results in a short shaft distance dimension or DBSE „Distance Between Shaft Ends“.

The coupling halves identical in design are made of cast iron making the ROFLEX N standard type particularly low-priced. The shaft coupling is mounted simply in that the hubs are pushed on the shaft and axially fastened via setscrews.

The ROFLEX N transmits torques up to 5,000 Nm reliably.

A prerequisite for use in general mechanical engineering and the pump industry is the ATEX approval as well as the EAC declaration which are both met by ROFLEX N and ROFLEX SH.

The type examination certificate is attached to the assembly instructions. Both can be found at the menu item „Service“

Function of a failsafe shaft coupling:

The ROFLEX shaft coupling is composed of two hubs the cams of which are inserted in the tailor-made clearance of the other hub half each. 
This short design of the shaft coupling allows to combine shafts having a particularly short shaft distance dimension. The elastomer located between the cams transmits the torques while compensating for any kind of displacement.

Component variance of a failsafe shaft coupling: 

High adaptability with small variance by an optimally graded construction kit system: The elements of the ROFLEX® shaft coupling of one size can be combined with each other without any problem. As a consequence various shaft distances can be generated by the same basic component.
