REVOLEX® is a torsionally-flexible, failsafe pin & bush coupling. It can be plugged in axially and is characterized by its short design. In addition, REVOLEX® allows for an easy disassembly of the elastomer rings including the pins while being assembly. The REVOLEX® coupling compensates for every kind of shaft misalignment while transmitting the torque safely.

The coupling consists of two hubs that are identical in construction. The pins and pocket holes alternate on the outer pitch circle. The torque is transmitted via the steel pins with their taper elastomer rings and the corresponding bores in the bush hub.

As a result all kinds of shaft misalignment, for example caused by inaccurate alignment of the driving or driven elements, is compensated for reliably and vibrations and shocks are compensated for excellently.

The coupling is maintenance-free and is used in general engineering and the pump industry, conveyor technology, etc. For an optimum adjustment to the different applications, 21-off sizes are available covering torques up to 1,220,000 Nm. Apart from the standard programme customized solutions are available.
