Sumitomo Heavy posts ¥55bn operating profit as robot gear orders steady

Sumitomo Heavy Industries reported ¥54.98 billion in operating profit on ¥834.23 billion in consolidated net sales for the nine months ended Sept. 30, a 6.6% operating margin. The Tokyo manufacturer said factory automation orders stabilized across its precision reduction gear lines, which supply cycloidal speed reducers to industrial robot builders.

Orders for automated guided vehicle drives and semiconductor assembly components offset softer equipment purchasing in European machinery markets, according to the company. Profit attributable to owners of the parent reached ¥28.54 billion.

Sumitomo Heavy does not break out standalone quarterly sales or unit shipments for robotic reducers; those figures sit inside its Drive Technologies segment, which makes Fine Cyclo zero-backlash gearboxes. The company also joined the Kyoto Humanoid Association with Waseda University, Renesas Electronics and Murata Manufacturing to develop joint reducers and high-torque actuator packages.

For robot cell builders, the report points to steadier lead times on cycloidal reducers used in six-axis welding arms and heavy-payload foundry robots. Sumitomo trimmed its full-year guidance to ¥1,173 billion in net sales and ¥80 billion in operating profit, leaving roughly ¥25 billion to book in the fourth quarter.
