When Helical Products Company revolutionized coupling technology with the HELI-CAL Flexure Concept over 50 years ago, design engineers around the world discovered more reliable alternatives to traditional couplings/couplers, U-joints, and precision springs. Today, millions of HELI-CAL Flexures can be found in applications ranging from satellite instruments and scientific apparatus to conveyors and oil-field equipment.
 
The most demanding extension, compression, torsion, and lateral bending and translation spring applications can benefit from HELI-CAL Flexures because of their superior function and inherent versatility. HELI-CAL Flexures benefit overall system designs through enhanced functionality, increased precision and cost reduction as a result of true engineering expertise. Predictable and repeatable elastic performance is close at hand when one chooses HELI-CAL Flexures. 
 
The final result is an elegant, single-piece component designed for the full extent of your workload characteristics in all operational modes, not just a single functional phase. The strengths fundamental to the original HELI-CAL Flexure Concept can expand your engineering horizons. Now you can dream!
