Recently, the project "R&D and Application of Wind Turbine SRB Main Shaft Bearings," led by MAANSHAN JING WEI SLEWING BEARING CO.,LTD was appraised by experts organized by the Anhui Province Machinery Industry Federation. It was recognized as having overall technology reaching international advanced and domestic leading levels. This achievement marks a significant breakthrough for China in the key field of wind turbine main shaft bearings, providing strong support for promoting the localization of wind power equipment. The project focuses on long-standing "bottleneck" problems in the manufacturing of wind turbine main shaft bearings—specifically, the lack of soft-band quenching technology. Through multiple improvements and experimental verifications, Jingwei, in collaboration with partners, successfully developed equipment and a supporting process system for soft-band-free quenching with independent intellectual property rights. This effectively breaks through foreign technological monopolies and addresses industry pain points such as high costs and low efficiency in traditional quenching processes. In terms of innovative achievements, the project realizes three major breakthroughs: · ‌Material System Innovation‌: By adding trace alloy elements, a new type of ring material with high strength and high hardenability is developed, better matching the requirements of soft-band-free induction quenching processes. · ‌Process Control Breakthrough‌: High-precision accompanying tracking technology for quenching inductors is developed, overcoming the challenge of controlling the uniformity of hardened layers in large bearings. · ‌Design Method Upgrade‌: A new bearing design software is independently developed, effectively solving system coupling deformation problems under complex working conditions. Currently, the product has passed certification by the Beijing Jianheng Certification Center, and all performance indicators meet the 20-year service life requirements for onshore wind turbine main bearings. It has been applied in Mingyang Smart Energy Group. The project has cumulatively applied for 4 invention patents, obtained 1 authorized utility model patent and 3 software copyrights, and participated in the formulation of 1 national standard, demonstrating good technical maturity and industrial application prospects. It is understood that in recent years, Jingwei has continuously increased R&D investment in areas such as wind turbine SRB, TRB, DTRB main shaft bearings, and intelligent tracking photovoltaics, achieving multiple progress results. The company's photovoltaic tracking reducers have been exported to many countries in Europe, North America, South America, the Middle East, and the Belt and Road region, generating hundreds of millions of yuan in foreign exchange revenue annually. This technological breakthrough not only reflects Jingwei's innovative strength in the field of high-end bearings but also provides a reliable and c...

‌The National and Group Standards for Wind Turbine Seals and Smart PV Tracking Systems, in which Jingwei participated in drafting, have been officially released. ‌ Recently, the National Standardization Administration and relevant industry organizations officially released the ‌National Standard GB/T 33154-2025 "Rubber Seals for Yaw Bearings and Pitch Bearings of Wind Turbines"‌ and the ‌Group Standard T/CI 1083-2025 "Smart Tracking PV Mounting Systems."‌ MAANSHAN JINGWEI NEW ENERGY DRIVE EQUIPMENT Co., LTD . and its subsidiary MAANSHAN JINGWEI NEW ENERGY DRIVE EQUIPMENT Co., LTD served as key drafting units, deeply involved in the technical review and drafting of both standards, marking another recognition of the company's technical strength in wind turbine sealing and PV tracking systems. The two standards focus on key components and technological systems in the new energy industry, aiming to further improve the technical specification system for wind and PV sectors and provide crucial technical support for achieving the "dual carbon" goals. ‌GB/T 33154-2025‌ systematically regulates the performance requirements of rubber seals for yaw and pitch bearings throughout their lifecycle. The new standard introduces specifications for multi-lip seal structural design, establishes a precise dimensional tolerance system, and sets stricter finished product performance indicators, meeting the sealing reliability demands of wind farms in extreme environments such as high/low temperatures, strong UV exposure, and high salt spray. ‌T/CI 1083-2025‌ focuses on the intelligent upgrade of PV tracking systems, clarifying key performance parameters such as tracking accuracy, wind resistance, and seismic resistance, promoting the expansion of mounting systems from flat terrains to complex scenarios like mountainous and water surfaces, and providing an important technical basis for improving the overall power generation efficiency and system reliability of PV power plants. As an enterprise in the wind and PV new energy sector, Jingwei has long been deeply engaged in R&D for critical technologies in sealing systems and new energy equipment, continuously increasing R&D investment, and building a full-chain technical system covering material formulation, structural design, and performance testing. During the drafting of ‌GB/T 33154-2025‌, Jingwei actively contributed its engineering experience in sealing structure and material performance, collaboratively promoting the implementation of related technologies. In ‌T/CI 1083-2025‌, it assisted in demonstrating technical parameters for the adaptation between tracking systems and seals, effectively driving the transformation of corporate innovation achievements into industry-wide norms. In the future, Jingwei will leverage the release of these two standards to continue deepening R&D investment, promoting the coordinated improvement of technological innovation and standardization in the new energy ...
