Product Display
This tiny component, just 1.5 mm in diameter, could be a critical bottleneck in the trillion-dollar humanoid robotics ecosystem.
From point contact to line contact.
It’s like a row of hands working together to distribute the load, ensuring more uniform pressure and delivering significantly
Smaller. Stronger. More Precise.
Inside, the main shaft is like the Sun, while the threaded rollers surrounding it are like planets, rotating on their own axes
It is the dense engagement between these threads that transforms rotational motion into smooth, precise linear thrust.
Application Cases
Planetary roller screws provide lightweight, high-performance motion transmission solutions for humanoid robots, with broad applications in industrial automation, medical equipment, consumer electronics, and the low-altitude economy.
