Our most popular product, using single piece construction, the HELI-CAL Flexure concept, and any combination of bore diameters, materials, or end connections.
If our Standard Coupling is not the right size or you need more performance then inquire with Helical about designing and manufacturing a Custom Coupling to fit your specific requirements. Our Application Engineers will work with you to choose the best material, incorporate your specific features and attachments, and design a HELI-CAL Flexure to provide you with the optimal flexible coupling for your application.
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.
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.
