State of the Gear Industry 2026

The gear industry navigates uncertainty, finds pockets of strength, and bets on automation

Of the 137 respondents to our annual gear-industry survey, the message was clear: tariffs are the defining challenge of 2026. But the frustration runs deeper than the duties themselves. Manufacturers can absorb cost increases; they can’t absorb chaos. When rules shift weekly and exemptions evaporate overnight, planning becomes guesswork. One respondent captured the exhaustion: “In 2025, they were all over the place, without warning, up and down. Terribly disorganized.” Yet within this turbulence, distinct currents run strong. Defense and aerospace work has surged. Oil and gas, buoyed by loosened regulations, is “very active” according to multiple respondents, with mobile power units and gas compression driving demand. Overhaul and repair business is booming—when new equipment becomes expensive or hard to source, companies keep existing machines running longer, and that means gears.

¡Rápido!

With many of its precision gears produced in small lot sizes, Spanish gear producer Engranajes Juaristi S.L. depends on Gleason machines for exceptional speed and flexibility.

Design

For cylindrical gears, speed-increasing transmission stages are well known, and regarding profile shift, preferred pressure angles, and helix angles a set of rules applies, which is not much different from the rules for speed reducers. It is important to acknowledge that basically, a speed increaser has to be designed just like a speed reducer, but then the gear with the lower number of teeth is the output. Of course, the torque and the speed of the gear with the lower number of teeth (output) and the gear with the higher number of teeth (input) must be the same as if this transmission was used as a speed reducer. In the case of straight bevel gears, spiral bevel gears, and hypoid gears the same rules apply with some additions. Spiral bevel gears have many applications as speed increasers.

Overall developments and widespread public awareness of man-made climate change are transforming the way people think. The awareness has inspired a shift towards a more ecologically sustainable way of life. Driven by policymaking and technological innovation, ambitious efforts are underway to reduce greenhouse gas emissions to curb the rise in average temperatures. A key focus of these efforts is the mobility sector. 

Manufacturing

As the gear and power transmission industries evolve, companies worldwide face a critical challenge: how to ensure the workforce is skilled, prepared, and ready to tackle increasingly complex manufacturing processes. From digital manufacturing and automation to generational turnover, the demand for technically proficient employees has never been higher. In response, the Motion + Power Technology Association (MPMA) redeveloped its Workforce Training Series, modernizing its most popular on-demand courses with updated content, high-quality media, and a flexible, self-paced delivery model.

Heat Treating

Quality control, EV components, energy consumption and material influences are just a handful of topics being discussed in heat treating today. New heat treat methods and global trends will be the topic of conversation later this year at Heat Treat 2023. Here’s a round-up of some stories circulating across key market segments.
