The Rising Robotic Reducer Market

- Nov 07, 2020-

As a functional part of the industrial robot center, the reducer accounts for 33%-38% of the entire robot production cost. At present, the sales of industrial robots are increasing, and the potential demand for reducers is increasing accordingly year by year.

The power source of an industrial robot is generally an AC servo motor, and it is driven by pulse signal, the servo motor itself can realize speed adjustment. Why do industrial robots still need a reducer?


The industrial robots need to complete process tasks reliably in production and ensure process quality, they  have very high requirements to the positioning accuracy and repeatability. Thats why it needs fine reducers.

Fine reducer enables the servo motor to run at an appropriate speed, reduces the speed to the rate that required by each part of the industrial robot, and generate greater torque. Compared with general reducer, robot joint reducer requires short transmission chain, small size, large power, light weight and easy control.

With the rapid development of the domestic economy in recent years and the increase in exports of the heavy machinery industry, as an important basic industry, reducer has developed rapidly. Due to strong downstream market, reducer manufacturers are expanding their production and sales plans, and their processing capabilities and skill levels keep improving.

According to the growth of industrial robot sales and inventory, it is estimated that by 2025, the demand for industrial robot reducers will reach 1 million units which is about 1.2 billion USD.

According to statistics from national departments, from 2015 to 2018, the demand for reducers in Chinese industrial robots reached 236,000 sets, 296,000 sets, 369,000 sets, and 462,000 sets. In addition, according to the calculation of the general service life of 8-10 years in the domestic reducers inventory, the domestic market demand for fine reducers will exceed 1 million units in the future, and the annual market sales will exceed 1.5 billion USD.

So far, the domestic reducer has passed the market assessment for 3-4 years, and the inspection function includes noise, accuracy, rigidity, etc. Driven by the development of the robotics industry, domestic manufacturers have realized the importance of the reducer as core component and have made continuous progress. In terms of harmonic reducers, some domestic manufacturers have gradually narrowed the gap with foreign manufacturers, and are constantly seeking break on RV reducer.

In the future, driven by industrial robots, Chinese robot reducer industry is expected to grow rapidly and market demand will continue to increased. But for domestic enterprises, the localization development still has a long way to go.
