Bearings & Bearing Components that We Manufacture
Custom solutions that fit your needs
We have strong capabilities in designing and producing wind turbine main bearings, yaw bearings, pitch bearings and gearbox bearings. As one of the leading suppliers of wind turbine bearings, we are backed by robust technical expertise and a dedicated R&D team that focuses on the production of large slewing bearings. We invest heavily in research and development each year to drive continuous innovation and improvement.
We have a strong foundation in creating original products, consistently increasing our investment in R&D and bringing in talented researchers. With multiple research centers and technical teams, we're focused on enhancing our R&D capabilities and building an exceptional development team. Our company, along with subsidiaries Shengjiu Forging and Haozhi Machinery, is recognized as a high-tech enterprise. Every year, we allocate significant resources to ensure our teams can drive product innovation and technological progress.
We’ve developed a range of wind turbine bearings from 1.5MW to 18MW, achieving import substitution. This includes pitch and yaw bearings, as well as 2-5MW three-row cylindrical roller main bearings and 3-18MW single-row tapered roller bearings, all now in mass production. Our 12MW offshore typhoon-resistant main bearings have successfully tackled key technical challenges in China’s high-power wind turbine sector and have been installed. We’ve also validated and mass-produced 5-7MW spherical roller bearings. Currently, we’re focusing on developing bearings for wind turbines over 20MW, ensuring we’re ready for the next generation of larger turbines.
Our generator's main bearing, pitch bearing, and yaw bearing are all developed by ZZ Company and have been put into use in many regions.
We have delivered large spherical sliding bearing forgings for the tunnel project. The bearing, specifically designed for a shield tunneling machine with a diameter of 15 meters, weighs 88 tons. The production of the heaviest and largest precision rolled ring forgings marks a significant achievement in our engineering capabilities.
ZZ is your trusted partner in manufacturing high-quality slewing bearings and custom components. Whether it's wind energy, tunnel boring, or marine applications, we deliver reliable solutions tailored to your specific needs and budget.
