RAFLEX® flexible disk couplings
The alternately bolted plate sets of the coupling are made of stainless spring steel. Due to the layered structure of the specially shaped plates, 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® steel lamina couplings are available in standard 3-bolt, 4-bolt and 5-bolt designs. The number of bolts always refers to one side of the coupling. The different lamina variants allow the optimum coupling to be selected for each application. The number of pins determines the transmittable torque as well as the misalignment capability of the coupling.
