Other Helical Products:

U-Joints – The “HELI-CAL Flexure” is an advanced u-joint solution that generally exceeds the capabilities of traditional u-joint designs. A Helical u-joint is really a flexure capable of over 5° of angular misalignment. It may accommodate up to 90° of angular misalignment in certain circumstances. This type of u-joint will also compensate for axial and parallel misalignment.


Machined Springs – The most demanding compression, torsion, and lateral spring applications can benefit from the HELI-CAL Flexure concept. Overall system designs can be enhanced because HELI-CAL Flexures increase precision, require less space, and reduce costs.
