Our high-speed precision bearings are powering advancements across multiple sectors. In the wind energy sector, Jilin Zhongye’s specialized bearings are now integral components in the main shafts of large-scale turbines deployed by Envision Energy and Goldwind in Inner Mongolia and Xinjiang. These bearings have successfully operated under extreme temperature fluctuations (-30°C to +60°C) and high vibration levels, maintaining operational integrity over 8,000 hours without maintenance. In the automotive industry, our bearings are used in transmission systems for electric vehicles produced by CATL and BYD, contributing to quieter, smoother gear shifts and improved energy efficiency. A case study from a major Chinese EV manufacturer revealed a 12% increase in drivetrain efficiency after replacing imported bearings with our domestically developed high-speed variants. In the railway sector, our bearings support traction motors in CRRC’s high-speed rail trains, delivering reliable performance on routes between Beijing and Shanghai. Notably, during a 2023 performance audit, our bearings achieved a 99.7% uptime rate—surpassing international benchmarks. Moreover, in the manufacturing field, our bearings are employed in precision machining centers used by XCMG and SANY, enabling tighter tolerances and faster cycle times. These real-world validations underscore our commitment to quality, innovation, and customer-centric engineering, positioning Jilin Zhongye as a trusted partner in China’s drive toward technological self-reliance and industrial upgrading.
--- Heavy-Duty Bearings for Tough Conditions ---
• Durability and Load Capacity:
Engineered for the most demanding industrial applications, Jilin Zhongye’s heavy-duty bearings are built to withstand extreme loads, shock, and harsh environmental conditions. Our six-row cylindrical roller turntable bearings, designed with precision-machined outer ring gears, are specifically tailored for ultra-heavy machinery such as crawler cranes used in mining and port operations. One notable example is their deployment in a 1,200-ton capacity crane at the Port of Dalian, where they have endured continuous 24/7 operations for over three years without failure. The unique load distribution—two rows handling axial forces, two radial, and two angled to resist overturning moments—allows these bearings to manage multi-directional forces up to five times greater than conventional slew bearings. This structural superiority was validated through finite element analysis and full-scale fatigue testing conducted at our in-house ZWZ X MAHR metrological lab. In another instance, our spherical plain thrust bearings were installed in vertical motor assemblies for a large-scale cement plant in Henan Province, where they successfully carried axial loads exceeding 200 tons while compensating for installation misalignments of up to 2.5°. The self-lubricating PTFE-inlaid surfaces ensured zero maintenance for over 18 months, drastically reducing downtime. These bearings also play a critical role in mining excavators manufactured by Shagang Group, where they endure abrasive dust and impact loads. Field data shows a 40% improvement in service life compared to legacy models. Our robust design philosophy, combined with high-strength alloy steels (e.g., 40Cr and 10.9-grade bolts), ensures long-term reliability. Each product undergoes stringent endurance testing under simulated real-world conditions, including vibration, temperature cycling, and overload scenarios, guaranteeing durability in the toughest environments.

• Sustainability and Efficiency:
As a key player in China’s green energy transition, Jilin Zhongye Bearing Technology Co., Ltd. has pioneered innovative bearing solutions tailored for modern wind power systems. Our wind turbine main shaft bearings, developed using advanced materials and optimized geometry, are now widely adopted by leading renewable energy companies such as Mingyang Smart Energy and SPIC. A landmark case occurred in 2022 when our bearings were integrated into offshore wind farms off the coast of Jiangsu, operating in saltwater environments with high humidity and corrosive exposure. Despite these challenges, the bearings maintained a 99.2% operational availability over a 12-month period—exceeding industry averages. The secret lies in our proprietary surface treatment process and sealed lubrication system, which prevent moisture ingress and extend grease life by up to 50%. Additionally, our lightweight yet high-load-capacity designs reduce overall turbine weight by 8%, improving energy capture efficiency. In collaboration with Wafangdian Bearing Group, we leveraged shared R&D platforms—including the Global Bearing Joint Simulation Technology Center—to simulate real-time load dynamics and optimize bearing performance under variable wind conditions. This partnership enabled us to develop a predictive maintenance model that reduces unplanned outages by 35%. Furthermore, our focus on sustainability aligns with national “Dual Carbon” goals: clean energy utilization in our production facilities reached 32% in 2023, and all new bearing models are designed for recyclability. These innovations not only enhance turbine reliability but also contribute to lower levelized cost of energy (LCOE), making renewable power more competitive. By combining cutting-edge engineering with environmental responsibility, Jilin Zhongye is helping shape a cleaner, more efficient future for global wind energy.
