The RODOFLEX metallic bellows coupling program encompasses several series, starting from very small couplings with an outer diameter of just 12 mm, up to the largest couplings suitable for power drives with a maximum nominal torque of 340 Nm.

The RODOFLEX AMKN miniature series feature a particularly lightweight design, with hubs made of aluminum, firmly bonded to a copper-zinc alloy metal bellows. They are available in versions with radially clamping set screws on the shaft or also in a collar clamp version, which ensures a reliable coupling without leaving permanent marks on the connected shafts. These couplings are free from backlash and wear, easy to install, and always comply with the maximum allowable misalignment values, for torques ranging from 0.25 to 12 Nm and for shaft diameters from 1 to 24 mm.

The RODOFLEX power transmission couplings in the ATMK and ATMN series feature hubs welded around the entire circumference to the metal bellows, all in stainless steel. There are four options for the coupling hubs: collar clamp or two semi-collars depending on the size, tapered bushing, keyed hollow shaft coupling, and finally a flange version with a ring of threaded coupling holes. The all-stainless steel construction makes them resistant to corrosion, thus ideal for use in the presence of aggressive agents, in vacuum environments and/or cleanrooms; their temperature resistance up to 300°C allows for use even under the most severe conditions, such as in certain chemical industries. The range of RODOFLEX power transmission couplings offers solutions for nominal torque moments from 10 to 320 Nm, with a safety factor of 2.5 already accounted for, considering peaks resulting from acceleration and rotational reversals, for shaft diameters from 8 to 110 mm.
