Sumitomo G9B200KH Gear Head

The Sumitomo Astero G9B200KH Gear Head is a parallel-shaft intermediate gear head in Sumitomo's Astero line, designed to pair with compatible Astero servo motors to boost torque and tailor speed through fixed reduction ratios. When used as an intermediate gear head, it provides a rated torque up to 19.60 N·m (200 kgf·cm), enabling higher torque output without increasing motor size. The G9B200KH is part of the G9B□KH family, which supports parallel-shaft configurations with reduction ratios ranging from 3:1 to 200:1; right-angle variants offer 5:1 to 240:1. A key feature of Astero components is their modular design—the motor and gear head are detachable for easier handling during installation and maintenance. Typical applications for this gear head include precision motion control and torque extension in automation systems, packaging machinery, robotics grippers, and conveyor/indexing setups where a compact footprint and reliable torque delivery are required.
