LTZC wind turbine bearings achieve new breakthrough

LTZC Achieves Breakthrough in Wind Turbine Bearings

November 2025 – LTZC, a leading manufacturer of precision bearings, is proud to announce a major breakthrough in its wind turbine bearing technology. The company's new slewing bearing solution, specifically tailored for wind turbine applications, significantly improves the performance, durability, and efficiency of wind energy systems worldwide.

With the accelerating growth in demand for renewable energy, wind turbines play a crucial role in the global transition to sustainable energy. However, wind turbines operate under extreme weather conditions for extended periods and have extremely high maintenance costs, often placing stringent requirements on bearing materials, lubrication, and sealing.

Key Features of LTZC's New Wind Turbine Bearing Technology

LTZC's newly developed slewing bearing is designed to meet the demanding requirements of modern wind turbines. In modern wind turbines, extreme environmental conditions and continuous rotation place enormous stress on the bearing system. This new product series features several key improvements:

Higher Load Capacity: LTZC wind turbine slewing bearings are primarily three-row roller slewing bearings and crossed roller slewing bearings. Their rolling elements are made of GCr15, and their structure boasts superior load capacity. LTZC wind turbine slewing bearings have been exported to countries such as Spain and Germany, making them an ideal choice for large, high-power wind turbines deployed globally. These bearings are designed to withstand high radial and axial loads, ensuring the stability and safety of wind turbine operation even under the harshest conditions.

Optimized Bearing Types and Sizes: LTZC has expanded its bearing size range from 300mm to 15000mm, providing customized solutions for onshore and offshore wind turbine applications. From compact, lightweight bearings suitable for small wind turbines to large bearings for the latest megawatt-class wind turbines, LTZC bearings offer optimal performance for wind turbines of all sizes.

Enhanced Durability and Service Life: One of the most significant improvements in LTZC wind turbine bearings is their enhanced durability. The new design incorporates advanced ball bearing technology, significantly reducing long-term wear. This improvement translates to longer maintenance intervals and an extended overall service life, providing turbine operators with a more cost-effective solution.

Corrosion Resistance: For offshore wind turbines operating in highly corrosive environments, LTZC's slewing bearings feature special coatings, such as black oxide and zinc-nickel alloy coatings, to prevent rust and performance degradation. This characteristic ensures the bearings maintain their integrity and performance even in salt spray, humid, and windy conditions.

Precision Engineering: LTZC's expertise in precision ball bearing manufacturing enables smaller tolerances and smoother rotation, thereby improving operating efficiency and reducing energy loss. The company's advanced machining capabilities ensure that each bearing is manufactured to stringent specifications.

How LTZC addresses the challenges of wind turbine bearings

Wind turbine bearings face unique challenges that distinguish them from bearings in other industries. Unlike many other types of machinery, wind turbines are subjected to continuous and varying forces and operate for extended periods in extreme environments, including wind loads, gravity, and fatigue from continuous motion. Bearings in wind turbines, particularly slewing bearings, must withstand these extreme conditions and operate stably without compromising performance.

LTZC has invested heavily in research and development to create bearings that meet and exceed the stringent performance requirements of the wind energy industry. The company's next-generation slewing bearings are specifically designed to address issues such as oscillation and long-term wear, reducing wear, extending equipment life, and lowering maintenance costs while maintaining bearing performance. These solutions ensure greater reliability, less maintenance intervention, and more predictable operating performance.
