HELI-CAL® Flexible Shaft Couplings

A New Angle on U-Joints
The HELI-CAL® “Flexure” is an advanced and unique u-joint solution that generally exceeds the capabilities of common u-joint designs. A HELI-CAL® 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.

Wire Wound Vs Spring Machined Springs
This white paper addresses the high points of choosing between Machined and Wire Wound Springs, and goes into further detail regarding the unique differences that can significantly affect design considerations.

Generate Only Enhancement Program
As the old adage tells us, a chain is only as strong as its weakest link. While this bit of wisdom applies to a wide variety of situations, it rings particularly true for components in an engineered system. Each part has a role to play and an essential burden to bear. From medical machinery components to aerospace applications, one common weakness can create critical failure: EXCESSIVE RIGIDITY. A universal problem calls for a universal solution; one that provides essential flexibility for all of your precisely designed components. This solution is our proprietary Heli-Cal® Flexure technology, implemented through our unique Generate Only product enhancement program. Our Flexure helps prevent premature component wear, likelihood of damage, motor seizure, bearing failure, elimination of vibration failures, compensation for coefficient linear expansion, and many other benefits.
