German SERAX coupling SERAX model SERAX price

The SERAX coupling connects two half-couplings with several sets of diaphragms (thin stainless steel plates) using bolts in an alternating arrangement. Each set of diaphragms consists of multiple stacked layers. The diaphragms are categorized into link-type and solid-piece types of various shapes. The diaphragm coupling compensates for the relative displacement between the two connected shafts through the elastic deformation of the diaphragms. It is a high-performance flexible metallic element coupling that requires no lubrication, features a compact structure, high strength, long service life, and zero rotational backlash. It is unaffected by temperature or oil contamination, offers acid, alkali, and corrosion resistance, and is suitable for shaft systems operating in high-temperature, high-speed, and corrosive media environments.
