Darker bar: ahead of the other company on that measure.
SPINEA is a Slovakia-based manufacturer of high-precision cycloidal reduction gears and integrated DriveSpin actuators used in industrial robotics, automation, medical equipment and other motion-control applications. Its products are in serial production and have been supplied to major robot manufacturers including KUKA, ABB and Comau; in 2025 SPINEA launched the W series and published updated product documentation. The key distinction is its specialized European position in precision cycloidal gearing, although 2025 losses and limited entity-level revenue remain material open questions.
