The alternating bolted disk packs are made of stainless spring steel. Due to the layered structure of the specially shaped disks, these couplings compensate for axial, radial, and angular misalignments between the drive and working machines without generating high restoring forces. Highquality materials ensure a long service life even under the toughest of environmental conditions. The couplings fulfill the requirements of API 610 or 671, depending on the product family. Use in potentially explosive atmospheres is also possible according to ATEX.

Our RAFLEX portfolio is divided into two series  basic and turbo. The couplings in the DS series are especially suitable for industrial use in pumps, fans, presses, crane systems, generators as well as for marine applications. The turbo series is specifically intended for high-speed applications such as turbines, compressors or generators.
