High torsional stiffness and good radial flexibility are the proven benefits of the Huco Dynatork aluminium Step-Beam coupling but the latest generation of this design has been able to factor in even more benefits. The re-design of this product provides from 18-35 percent higher torque depending on the size, radial and axial compensation and zero backlash. The unique stepped radial slot configuration of the one-piece Huco Step-Beam coupling derives its high torsional stiffness from the straight beam design and its lateral flexibility from its helical counterpart. It has a big cross section that is in-shear providing a level of performance that is bordering on that of a bellows or membrane coupling. The low inertia and high accuracy of the Step-Beam continue to make it suitable for driving encoders. It is also remains a popular choice for applications that require electrical isolation and corrosion resistance. Manufacturing economies have also resulted in this latest design being introduced at a highly competitive price. This new aluminium Step Beam is available with standard bores up to 14 mm and with clamp fixing or set screw.
