In "Made in China 2025", plans are made to vigorously promote the development of the robot field. Focusing on the application demands for industrial robots (e.g., in automotive, machinery, electronics, hazardous materials manufacturing, national defense, chemical engineering, and light industry), special robots, as well as service robots (e.g., in healthcare, household services, education, and entertainment), efforts will be made to actively develop new products, advance the standardized and modular development of robots, and expand market applications. Breakthroughs will be achieved in technical bottlenecks such as the design and manufacturing of key components (including robot bodies, reducers, servo motors, controllers, sensors, and drivers) and system integration.
As one of the key supporting basic components for industrial robots, industrial robot bearings remain a relatively weak link in China. The localization of these bearings is crucial to the overall competitiveness of the domestic robot industry. In response to the development needs of the domestic robot industry, there is an urgent need to carry out the research and development of bearings supporting industrial robots and the key technologies for industrialization. On the premise of ensuring that all performance indicators of bearings reach the international advanced level, production costs should be reduced to lay the foundation for further improving the industrial robot industry system. The development of modern industrial robots tends to be lightweight; since bearings need to be installed in limited spaces, they must be small in size and light in weight (i.e., lightweight). However, at the same time, the performance requirements of robots—such as high load capacity, high rotational accuracy, high operation stability, high positioning speed, high repeat positioning accuracy, long service life, and high reliability—demand that the supporting robot bearings possess the performance characteristics of high load-bearing capacity, high precision, high rigidity, low friction torque, long service life, and high reliability. Lightweight and high performance are a pair of contradictory requirements.
According to the robot industry data released by the China Robot Industry Alliance, China's industrial robot sales volume reached 120,800 units in 2017, representing a 32.2% increase compared with 91,400 units in 2016. With the growing demand for industrial robots, it is estimated that China's industrial robot sales volume will reach 147,000 units in 2018, accounting for 37% of the global industrial robot sales volume. The future market for robot bearings in China is extremely broad. The rapid development of China's industrial robots will inevitably drive the rapid growth of the robot bearing sector. Precision bearings for robots mainly include: cross roller bearings and flexible bearings dedicated to harmonic reducers; tapered roller bearings, angular contact bearings, and needle roller bearings for RV reducers, etc.
Renben Group has been committed to the research and development of industrial robot bearings for many years. It has now developed a full range of products covering robot bodies, reducers, and joints, with product precision meeting the technical needs of industrial robot main engine customers. In the R&D and production practice of industrial robot bearings, the company not only optimizes and improves product characteristics to better provide high-quality services for industrial robot main engine customers but also jointly develops products with customers in the industrial robot main engine market. It improves the quality and technical level of bearing products by optimizing all links, including materials, design, heat treatment, testing, production control, and inspection, and its products have been recognized by customers. The group has accumulated experience in joint product R&D and is capable of conducting joint development and research of new products with customers.
Renben Group has continuously carried out industrial upgrading and achieved multiple breakthroughs in intelligent production, intelligent equipment, intelligent products, intelligent services, and intelligent management. It has built increasingly sophisticated intelligent manufacturing plants, which not only provide precision products for bearings in the robot industry but also contribute to the transformation and upgrading of Chinese bearing enterprises on the global stage, helping China's bearing manufacturing industry leap from a "global major player" to a "global power".
Adhering to the business philosophy of "continuous innovation", Renben Group is moving towards internationalization and making its own contributions to the realization of "Made in China 2025"!
