Even better performance from a lightweight, flexible coupling

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 popular product provides from 18–35 per cent higher torque depending on the size, superior radial and axial compensation than its forerunner, zero backlash and superior angular offset to 4 degrees.

The 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 and this provides 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 design being introduced at a highly competitive price. This new aluminium Step Beam therefore represents value for money and is available with standard bores up to 14mm and with clamp fixing or set screw.
