Maximizing torque-to-weight ratio and tilting rigidity, TwinSpin® G-series combines trochoidal gear arrangement with heavy-duty radial thrust bearing system each unit. This removes need for separate powertrain load support mechanics. Trochoidal gear contact profile provides ~50% simultaneous meshing, ensuring high torque transmission and backlash-free performance in precision motion control. There are 8 frame sizes with nominal ODs from 75–200 mm and rated torque from 34–950 Nm.
