Gearbox Makers Shift to Smart Solutions
Articles- May 13,26
Manufacturers are adapting to market challenges through sensorised solutions, software integration, acquisitions, and localisation to drive growth in the precision gearbox sector, writes Samantha Mou, Senior Analyst, Interact Analysis
The manufacturing economy has faced a series of challenges over the past three years, constraining growth in the precision gearbox market. In response, manufacturers are adopting proactive strategies to generate new revenue streams and prepare for future expansion. These include expanding product portfolios, pursuing vertical integration through acquisitions, and establishing localised operations.
Sensorised solutions for robotics
Manufacturers are diversifying their value propositions by offering solution-based products with integrated sensors, aimed at enhancing performance and reducing integration efforts for clients.
The continued expansion of the robotics industry has fueled the demand for sensorised gearboxes and actuator solutions. In particular, emerging companies in the sector are increasingly seeking solution packages for actuators, and precision gearbox suppliers are responding by developing products tailored to meet their demands. Leading manufacturers like Nabtesco, Harmonic Drive, and Nidec have all launched precision gearboxes or geared motors with built-in sensors, specifically targeting the robotics market.

The rise of cobots and humanoid robots is further accelerating demand. As cobots are deployed in delicate tasks such as polishing and precision assembly, the need for sensor-equipped systems has increased. While not all cobot axes include sensors, humanoid robot actuators typically require torque sensors for safety and precise control.
Enhancing software offerings
Beyond hardware, demand for monitoring software and predictive maintenance solutions is increasing.
Frequently offered with sensors as a package solution, monitoring software is used for analysing critical data provided by sensors attached to precision gear products, with the aim of optimising gearbox performance or ensuring precise control.
This technology is especially important in industries that rely on machines and gearboxes operating continuously, where unplanned downtime can be costly. Key sectors driving this demand include automotive and logistics.
Suppliers are investing in software capabilities to meet these requirements. For instance, Nabtesco introduced ‘virtual sensors’, a software-based solution that analyses torque and speed parameters, enabling condition monitoring and predictive maintenance without physical sensors.
Acquisitions for vertical integration
Manufacturers are also expanding their capabilities through strategic acquisitions to address broader market demands and strengthen competitiveness.
For example, Wittenstein’s recent acquisition of motion control supplier STXI Motion highlights the growing trend of vertical integration in the precision gearbox industry. Combining Wittenstein’s expertise in precision gearboxes with STXI Motion’s motion control technology is expected to enhance the company’s development of integrated actuator solutions, which are increasingly popular in the mobile robotics sector.
Similarly, Schaeffler’s acquisition of Melior Motion in 2022 expanded its robotics gearbox portfolio, enabling faster market penetration and strengthening its position in the humanoid robotics segment.
Establishing localised operations
To improve responsiveness, reduce costs, and ensure faster delivery, manufacturers are setting up production and service centres closer to key markets.
The Asia-Pacific and Americas markets are particularly attractive for manufacturers looking to establish localised operations. This strategy aligns with our forecasts that suggest higher growth in these regions over the next five years. Increasing production of robots, as well as semiconductor and electronics machinery, is driving this growth.

For instance, Schaeffler announced the establishment of a new subsidiary in China focused on humanoid robot bearings and gearboxes. Similarly, Leaderdrive has partnered with Tier 1 automotive supplier Minth Group in the US to set up a US-based assembly facility for humanoid robot actuators. Additionally, in late 2024, Nidec started production of strain wave gearboxes in China, targeting the local robotics market.
Final thoughts
The move toward sensorised products and software-driven functionality signals a clear convergence between mechanical engineering and digital capabilities. In this sense, the gearbox is evolving from a passive component into an active data-generating asset.
Manufacturers that successfully integrate hardware and software are likely to achieve stronger differentiation, while those remaining hardware-focused risk commoditisation.
Accordingly, precision gearbox manufacturers are repositioning themselves as system-level enablers in the robotics ecosystem, rather than pure component suppliers. This shift is not just a defensive response to a volatile manufacturing environment, it reflects a deeper recognition that future value will concentrate around integration, digital intelligence, and proximity to the end user.
