Extreme environments demand exacting standards. When designing for outer space, your components need to work the first time—and keep working, without fail. In zero gravity. Through extreme temperature fluctuations. Under immense pressure. That’s where Forest City Gear shines.

We’ve been manufacturing high-precision gears for space-bound systems for decades—trusted by teams launching missions to the Moon, Mars, and beyond.

From cryogenic cool to blistering heat, space is the ultimate stress test. That’s why our capabilities allow us to manufacture gears crafted with advanced materials, extremely accurate tolerances, and obsessive quality control. We deliver components that survive launch, thrive in orbit, and perform under the most punishing conditions imaginable.

We’re talking:

• Parallel axis gears, worms, splines, and more
• Micron-level tolerances
• Adherence to the highest AGMA quality standards
• From microns to 500 mm in diameter
• As fine as 0.127 module up to 8.0 module

Our gears have orbited the Earth, explored the far reaches of our galaxy, and kept critical equipment moving in space. We partner with aerospace engineers early—collaborating on materials, heat treatment, and surface finish to ensure every part is not just manufacturable, but mission-ready.

And our industry-leading metrology lab tests every component like it’s heading for launch. Because it very well could be.

From satellites and rovers to deployable mechanisms and robotic arms, Forest City Gear is the name behind some of the most trusted gears in space. When failure is not an option, we’re the team that makes sure your motion systems deliver.

There’s a reason the best of the best turn to Forest City Gear. Let’s launch something together.
