Short and service-friendly shaft coupling

With the ROFLEX, KTR LAUNCHES a new DIN 740 shaft coupling, characterised by its short design and its service-friendliness.

In addition to power transmission, the ATEX-approved torsionally flexible coupling compensates for misalignments and dampens torsional vibrations. The ROFLEX is available in two designs and currently in seven sizes for torques from 65 to 790Nm.

The short shaft coupling features input and output shafts which can be pushed together between 3mm and 6mm, depending on the size. The torque is transmitted via elastomer packages, which at the same time compensate for misalignments and dampen shocks and torsional vibrations. Should the elastomers fail due to extreme loads, the fail-safe coupling will continue to hold the torque.


The ROFLEX is available in two types: In type N, both the pocket and the cam part consist of standard hubs. In the SH SPLIT design, the cam hub is split with the hub being specifically and mechanically separated into two halves by 'fracture cutting' or 'cracking'. The resulting fracture surfaces centre both hub halves precisely with each other, which makes incorrect assembly almost impossible.
