RAFLEX® flexible disk couplings for low speed up to turbo applications

The RAFLEX® series is designed for various torque applications, with low or high speeds and can handle misalignments. The alternately bolted disk pack of the coupling are made of stainless spring steel. Due to the layered structure of the specially shaped disks, these couplings compensate for axial, radial and angular misalignment between the driving and driven machines without generating large restoring forces. 

High quality materials ensure a long service life even in the most demanding environmental conditions. Depending on the product family, the couplings meet API 610 or 671 specifications. They can also be used in potentially explosive atmospheres in accordance with ATEX.

RAFLEX® disk couplings are available in standard 3-bolt, 4-bolt and 5-bolt designs. The different disk variants allow the optimum coupling to be selected for each application. The number of bolts determines the transmittable torque as well as the misalignment capability of the coupling.
