In 2005, responding to the national "11th Five-Year Plan" energy strategy that called for vigorous development of megawatt-level wind power, SHCM pioneered the proposal to replace traditional rolling bearings with self-lubricating composite plain bearings.

In 2006, SHCM entered into a deep technical collaboration with the National Engineering Research Center for Power Generation Equipment of Harbin Electric Corporation, leveraging the combined strengths of both parties in material research and development as well as wind power equipment design. Together, they advanced the development of composite plain bearings for wind turbine main shafts. This collaboration led to the successful development of two key products:

Self-aligning plain bearings for 1.2MW and 1.5MW direct-drive doubly-fed wind turbine main shafts.

Three-way combined structure plain bearings for 2MW semi-direct-drive wind turbine main shafts.

Both product types were granted national invention patents in 2007 and 2010, respectively, making SHCM the earliest entity in China and globally to hold such patents.

To validate the practical performance of these products, in May 2010, a 1.5MW permanent magnet direct-drive doubly-fed pitch-controlled wind turbine—designed and manufactured by the National Engineering Research Center for Power Generation Equipment of Harbin Electric Corporation and equipped with SHCM's first-generation composite plain bearings for wind turbine main shafts—commenced real-world operational testing at the Ruihao Wind Farm in Bayanchagan, Daqing. After two consecutive months of rigorous testing, the bearing operating temperature remained stable at 55–60°C, with no abnormal wear, vibration, or other issues, fully demonstrating the reliability of the composite plain bearings in complex wind power environments.

In March 2011, a 2MW semi-direct-drive wind turbine equipped with SHCM's three-way combined composite plain bearings for wind turbine main shafts underwent a back-to-back test at Harbin Electric Corporation's electromechanical company. Throughout the test, key performance indicators such as bearing rotation accuracy and load-carrying capacity fully met the design requirements, further validating the product's compatibility with high-power wind turbine systems.
