Solutions using Helical Flexure Technology



Welcome To Helical

Inventors of the beam style flexible shaft coupling utilizing the HELI-CAL® Flexure. Whether used as a flexible coupling, u-joint, or machined spring, the
HELI-CAL Flexure utilizes its curved beam and one piece construction to meet design and performance requirements.

When used as a flexible coupling or u-joint, the
HELI-CAL Flexure is designed to transmit torque while compensating for angular misalignment, parallel offset, and axial motion between two shafts. HELI-CAL Flexures are available in a wide range of standard flexible couplings
to custom designed couplings, each engineered to meet the specific requirements of a unique application.

The Helical Machined Spring utilizes the same
HELI-CAL Flexure technology to provide the desired spring performance in compression, extension, torsion, lateral bending and lateral displacement modes. The ability to produce multiple-start Flexures solves many of the limitations associated with conventional springs.

One significant advantage of Helical’s flexible couplings, u-joints and machined springs is the one piece construction, which enables integrating customer specified end attachments (tangs, flanges, gears, removable caps, etc.) as well as unique bore configurations (D bore, hex, spline, shaft, etc.)
all into a single piece.
