In robotics, precision isn’t a luxury—it’s the whole game. Every movement depends on gears that are flawlessly precise, incredibly durable, and whisper-quiet. That’s where Forest City Gear comes in.

We’re a family-owned team of gearheads in Roscoe, IL who specialize in high-precision gears engineered to handle the most demanding robotic applications—on Earth, and way beyond.

Whether for dynamic industrial robots, space rovers, or collaborative cobots, our gears keep things moving smoothly. From parallel axis gearing and splines to worms and worm gears, Forest City Gear delivers the precision your robotic systems demand.

Micron-level tolerances? Check. Engineering expertise? Absolutely. Space-worthy durability? You bet.

Robots are getting smaller—and so are their gears. Lucky for you, we’ve mastered the micro stuff. We manufacture gears ranging from mere microns in size up to 500 mm in diameter, and as fine as 0.127 module up to 8.0 module at AGMA class 10 or higher. Translation? Forest City Gear specializes in tiny gears that pack an enormous punch.

We’ve been the go-to gear shop for robotics teams that demand the best—everything from high-speed automation to lunar missions. Why? Because we don’t just deliver parts. We deliver peace of mind.

Forest City Gear’s world-class inspection technologies, deep knowledge of heat treating and surface finishing, and obsessive attention to detail mean every gear is built to perform—and to last.
