There are four distinctive gear types that make up the Spiroid High Torque Gearing brand.

Spiroid®

The Spiroid brand is comprised of a pinion and a face-gear operating in non-intersecting and non-parallel axes.

Helicon®

Helicon is advantageous in that it broadens gearing design opportunities restricted by the physical limitations of conventional gearing.

Endicon®

Our Endicon brand of indexing and face coupling rings are used for inline power transmission where zero backlash is required.

Concurve®

Concurve gearing is an innovative gear tooth design offering advantages for coarse-pitch gearing applications.

The Spiroid® Process

Depending on your application and time requirements, Spiroid will follow one of only two process paths leading from initial inquiry to quotation. Each path requires active communication and discovery from both Spiroid and its prospective customers. Learn More…

I have used Spiroid gear products to solve many difficult design problems. These gears are a hidden gem that many designers are unaware of. The combination of compact form factor, high torque capacity, and customization has allowed me to design many highly integrated products. Being able to work hand-in-hand with the design staff to create customized gearsets is what sets Spiroid apart form any other gear manufacturer I have worked with.

Adam Couture, Wyss Institute, Harvard University

As a Consulting Mechanical Engineer, I have come across several design challenges over the last few years wherein there were needs for right angle drives with high speed reduction requirements. Realizing there are few ways to package a high speed reduction into limited space, I have consulted with ITW Heartland, the only domestic company manufacturing right angle Spiroid and Helicon gearing. Although there are other gear types one could consider, Spiroid gearing offers an excellent approach to difficult design problems. I have found the Spiroid Engineers to be very knowledgeable and eager to take on special designs in situations where off-the-shelf gears or gearboxes are not suited.
