Helical Products Company, Inc.

We make bar stock flexible through the design and manufacturing of flexible couplings, machined springs, and u-joints from one piece of material.

The HELI-CAL Flexure is a flexible helix (curved) beam machined from one piece of material into a specific configuration that incorporates special design requirements, performance features or characteristics.When used as a machined spring, the flexure provides desired and precise elastic performance in compression, extension, torsion, lateral bending and lateral displacement modes. Used as a flexible shaft coupling/coupler or u-joint, the flexure utilizes its curved beam to transmit torque while compensating for lateral, axial, and angular misalignment movements.A specific advantage of this technology - it enables customer specified end attachments, such as tangs, clamps, flanges, or threaded ends to be integrated into a single, multi-functional, motion control product.
