On September 18, 2019, a national standards working group meeting for the "Technical Conditions for Sliding Bearings Used in Rotating Machinery" was held at Hunan SUND Industrial Technology Co., Ltd., with the company responsible for drafting the standard. The meeting was chaired by the Standardization Institute of the Mechanical Science Research General Institute - China Machinery Productivity Promotion Center. Representatives from 17 organizations, including rotating machinery manufacturers, universities, research institutes, and sliding bearing suppliers (e.g., Dongqi, SAIC, Changjiang Power, Hangzhou Gas Turbine, Shenyang Blower, Jintongling, Xiangdian, Shanghai Electric, Nanyang Explosion-proof, Xi'an Jiaotong University, Taiyuan University of Science and Technology, Shenke, Bearing Factory, Taiyuan Heavy Industry Oil Film Bearing), and over 30 experts attended the meeting.

　　The experts attending the meeting discussed and revised each article of the draft "Technical Conditions for Sliding Bearings Used in Rotating Machinery". This is the first time Hunan SUND Industrial Technology Co., Ltd. has been responsible for the formulation and writing of a national standard. This has significantly enhanced the company's reputation and industry influence, strengthened its awareness of product and service quality, and played a crucial role in promoting the overall technical level and progress of China's sliding bearing industry.
