The transmission shaft is a high-speed, low support rotating body, so its dynamic balance is crucial. Generally, the transmission shaft needs to undergo a dynamic balancing test before leaving the factory and be adjusted on the balancing machine. For vehicles with front engine and rear wheel drive, the rotation of the transmission is transmitted to the shaft of the main reducer, which can be several joints connected by universal joints.

According to the "2021-2026 Development Prospect Strategy and Investment Risk Prediction Analysis Report of China's Transmission Shaft Industry" by Zhongyan Puhua, statistical analysis shows that:
In recent years, with the support of major national engineering and technology projects, China's automotive parts industry has continuously strengthened technological breakthroughs and innovation system construction through independent research and development, joint venture cooperation, and introduction of technical talents, gradually achieving breakthroughs in core technologies in some fields. The independent innovation system for Chinese brand automotive parts has initially taken shape. After years of development, most Chinese brand component enterprises have strong production and manufacturing capabilities and certain market competitiveness. Their system management and modular supply capabilities have been improved. Through differentiated multi-level development and concentric diversification promotion, they have achieved rapid expansion in scale and formed synergies among various segmented industries.

Domestic automotive parts companies have the industrialization capability of passenger and commercial vehicle parts systems, components, and subsystems, and have achieved comprehensive product coverage. After years of development, China has formed six major automotive parts industry clusters: Northeast China, Beijing Tianjin Hebei, Central China, Southwest China, Pearl River Delta, and Yangtze River Delta. In the context of increasing downward pressure in the automotive industry, the overall development of the automotive parts market is good, showing a medium to high-speed development trend. Under the trend of globalization, domestic automotive parts companies are adopting methods such as mergers and acquisitions, overseas mergers and acquisitions, equity joint ventures, and joint venture cooperation to accelerate their expansion and integration into the global parts procurement system and go global.

In recent years, the development speed of the market size of China's automotive parts industry has tended to stabilize. Driven by the steady growth of the automotive industry, the overall development of the parts market has tended to be good. However, in 2020, due to the epidemic, the market size of China's automotive parts industry declined to 4.12 trillion yuan, a year-on-year decrease of 3.7%.
After entering the 21st century, China's industry and manufacturing have continued to develop rapidly, and the level of automotive parts manufacturing has been continuously improved. In addition, China, with its manufacturing cost advantage, huge market demand, and favorable business environment, has attracted many well-known automobile and parts manufacturing enterprises from around the world to invest and build factories in China, greatly promoting the rapid development of China's automobile parts manufacturing industry. According to statistics from the China Association of Automobile Manufacturers, the total operating revenue of Chinese automobile parts enterprises increased from 2.2267 trillion yuan in 2012 to 3.744 trillion yuan in 2020.

The relevant departments estimate that the sales revenue of automotive parts in China will reach 4.9 trillion yuan in 2021.
