Gewinde Satelliten Antriebe AG (GSA AG)
Feldbrunnen, Switzerland maker of planetary roller screws founded 1982; part of the Gewinde Ziegler AG group, grinding threads since 1932.
Gewinde Satelliten Antriebe AG (GSA AG) is a Swiss manufacturer of planetary roller screws founded in 1982 and based in Feldbrunnen, Switzerland. The company operates within the Gewinde Ziegler AG group, whose thread-grinding business traces to 1932, with production sites in Horriwil and an additional facility in Grenchen added in 2016.
GSA's planetary roller screws, known in German as Rollengewindetriebe, provide higher load capacity, rigidity, and precision than comparable ball screws, with spindle leads ranging from 0.5 mm to 50 mm across four standard product types plus custom dimensions. The group added in-house hardening capability in 2019, so components are ground, heat-treated, and assembled on-site. GSA holds ISO 9001:2015 and ISO 14001:2015 certification, and its screws are used in electromechanical linear-drive applications that require high precision and repeatability, including robotics, aerospace, and industrial automation equipment.
The Gewinde Ziegler AG group employs approximately 70 people, including apprentices, across its Swiss facilities.
