RADEX-N NANA, Size 25 to 338
, RIGIFLEX-N A, Size 35 to 408

Product Description

The RADEX-N NANA / RIGIFLEX-N A coupling is a torsional flexible type coupling that compensates axial, radial and angular displacements of the connected machinery.The couplings could be fitted horizontally or vertically., , The RADEX-N NANA/ RIGIFLEX-N A are a lamina coupling designed with or without feather key. The lamina sets are connected to hubs and spacers. Dowel screws or special pins are alternately screwed to hubs and spacer enabling a combination of frictional engagement and positive locking., , The RADEX-N NANA/ RIGIFLEX-N A type coupling consists of two hollow hubs with integrated flange at one end, a spacer, laminated disc packs, bolts and nuts., , The coupling hubs are bolted at the flanges with flexible stainless steel laminated disc packs and the spacer., , The hubs bores have key ways for other shaft connections through feather keys and a slot on the hub to assist in screw clamping of the shaft.
