Original Innovative Technology

In 1958 Helical invented the beam style flexible shaft coupling by taking a novel concept and developing the method to generate the versatile HELI-CAL® Flexure into a piece of stainless steel.  Once the endless possibilities of a single piece Flexible Shaft Coupling were fully realized the evolution began. Learning that additional coils could be added to the HELI-CAL Flexure for greater misalignment led to the U-Joint product line that is capable of torque transmission up to a 90 degree angle. Further development of the manufacturing process led to a HELI-CAL Flexure with precise spring rates in compression/extension, torsion, bending, etc. From this the unique and revolutionary HELI-CAL Machined Spring® has evolved.  Read more about the Heli-Cal Story…
