01 Growing Demand for Compact Precision Gearboxes The precision gearbox market is seeing rising demand for compact, lightweight, and high-performance gearboxes as robotics and industrial automation expand. Manufacturers are focusing on improving torque density, rigidity, accuracy, and durability while reducing gearbox size. The growth of collaborative and humanoid robots is also creating demand for smaller gearboxes that can support multiple robotic joints and complex movements. For instance, in December 2025, Nabtesco introduced its RVmini and Monocrank precision reduction gear series to address growing demand for compact gearboxes in collaborative and humanoid robots. The company stated that its existing RV technology had more than 14 million units produced.
02 Growing Adoption Across Robotics and Automation Precision gearboxes are increasingly being used beyond traditional industrial robots, including machine tools, semiconductor equipment, medical systems, and automated production lines. Companies are developing products with lower backlash and improved positioning accuracy to meet these applications. For instance, Nabtesco's RV-N precision reduction gears provide backlash and lost motion of less than 1 arc-minute, supporting applications such as flexible manufacturing systems and precision machine tools.
June 2026 SEW-EURODRIVE expanded its precision planetary gearbox portfolio with new high-torque models designed for robotics, automation, and precision motion control applications, offering improved efficiency and compact design.
October 2025 Harmonic Drive Systems launched a new series of high-precision gearboxes engineered for collaborative robots and semiconductor manufacturing equipment, improving motion precision and reliability.
July 2025 Neugart expanded its precision planetary gearbox range with new compact models designed for servo-driven automation systems and high-speed industrial machinery.
