Swiss precision manufacturer of roller screws and linear motion components.
GSA (formerly Gewinde Satelliten Antriebe AG) is a Swiss precision engineering company specializing in high-performance planetary roller screws for demanding motion-control applications. Founded in 1982, the company develops compact, high-load linear actuation systems used in robotics, aerospace, industrial automation, medical devices, and other applications requiring exceptional precision, durability, and efficiency. Its planetary roller screw technology enables higher load capacity, longer service life, and greater positioning accuracy than conventional ball screws, making it well suited for humanoid robot actuators and other advanced electromechanical systems. As demand grows for powerful and compact linear actuation, GSA has become an important supplier within the global robotics motion-control ecosystem.
In the 2020s, GSA is increasingly relevant inside humanoid and advanced robotics conversations because roller screws are a key component in high-force linear actuators. Roboticos dataset tracks the company specifically for that supplier role inside the physical actuation stack.
GSA says it was founded in 1982 as an internationally active manufacturer of high-precision roller screws. The company also ties its roots back to the broader Gewinde Ziegler thread-grinding heritage, which predates GSA itself.
On its official site, GSA describes itself as an expert in planetary roller screws since 1982 and presents that product family as the center of its business. The companys relevance to robotics comes from supplying precision linear motion components into high-load electromechanical systems.
