The pace of large wind turbine units was accelerating,and the reliability of core compo-nents was increasingly important for wind turbine operations.Sliding bearings had the advantages of high load capacity,long life,easy maintenance,scalability and small size,and they had advantages and great potential for the reliable replacement of wind turbine main bearings key components pro-duced at home.The problems of main shaft rolling bearings in high-power wind turbines and the ad-vantages of using sliding bearings on the main shaft were analyzed herein.The technical methods and application status of wind turbine main shaft sliding bearing design,materials,lubrication,and exper-imental verification were present in detail,and the existing problems of high-power wind turbine main shaft sliding bearings and future development trends were summarized.It is expected to provide refer-ence for the digital design and industrial development of high-power wind turbine main bearings.
