Radex-N/ Rigiflex-N

PRODUCT INFORMATION

RADEX®-N is a backlash-free, torsionally rigid and maintenance free all-steel laminae coupling. The laminae packings of the RADEX®-N are supplied “artificially” pre-stressed from high-strength, stainless spring steel. Utilising FEM (Fininte Element Measurement) calculations, the laminae have been designed to compensate for high displacements yet maintain a high torsional rigidity with low restoring forces.

At the “heart“ of the steel laminae coupling are the laminae packings and their connection to the hubs or spacers. High-strength, special dowel screws are alternately positioned between hub and spacer to enable a combination of frictional engagement and positive locking. Thus a high power density with simultaneous easy displacement and low restoring forces is guaranteed.

With a similar all-steel laminae design, RIGIFLEX®-N was developed for pump drives in particular and correspond to the regulations of API 610 and API 671 optionally (API = American Petroleum Institute).

Both RADEX®-N and RIGIFLEX®-N cover torques from 60 Nm to 280.000 Nm are covered in 23 sizes for an optimum adjustment to different applications. Torques of 330,000+ Nm are possible in our RIGIFLEX® HP (High Power) design for high speed applications such as compressors and turbines.

ATEX Explosion-Proof Use

RADEX®-N & RIGIFLEX®-N are both suitable for power transmission in drives used in hazardous areas – certified according to EC standard 94/9/EC (ATEX95) as units of category 2G/2D, for use in hazardous zone areas 1, 2, 21 and 22. The all-steel design also allow for use in drives with temperatures of up to 280 °C.

IN COUNTRY SUPPORT

With a presence in Bahrain KTR Couplings can offer a technical design support and maintenance support services. This means we can offer a level of service for replacement parts and design support that our competitors cannot. In fact, KTR has a truly international reach from which to support your business – 24 dedicated global subsidiary offices and a sales presence in over 60 countries worldwide. This is another reason why international businesses choose KTR Couplings.

TRUE COST OF COMPONENT FAILURE

At KTR Couplings we understand that component failure costs far more than the value of the component replacement. Some failures can lead to protracted system down-time that causes a significant loss to the business. So overall the cost of the component is a very small consideration and the use of more expensive components which provide higher performance, improved reliability and longer life can in fact save your business money.
