METALFLEX is an innovative coupling for high performance applications requiring repeatability, accuracy in positioning, motion and synchronization control at high speed.
METALFLEX is an assembly of two aluminium clamping hubs and a thin walled stainless steel bellow, which remains rigid under torsional load, but it is axially, radially and angularly flexible in order to compensate misalignments within the connecting shafts: the result is a zero backlash high torsional stiffness low inertia coupling.
The advantage of METALFLEX against other zero backlash couplings on the market, as beam or curved jaw couplings, is a higher torsional stiffness, key factor for the precision in positioning: a higher torsional stiffness means more accuracy in the motion transmission from the motor to the driven component.
During installation, before tightening the screw of the second hub, check that the coupling remains axially relaxed. To grant the catalogue torque transmission between the shafts and the coupling, clean and degrease the contact surfaces on the shafts and on couplings’ bores, and tighten the retaining screws with a torque wrench.
