Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.

around the current wind power development facing the market
eijing Metallurgical bearing manufacturer exhibitors 2012 Beijing International Wind Energy Conference
November 15, 2012 to 17, by the China Renewable Energy Association Professional Committee, China Resources Comprehensive Utilization of Renewable Energy Industries Association Professional Committee, National Renewable Energy Centre, the Global Wind Energy Council, China Electronic Information Industry Development Research Institute jointly sponsored by the 2012 Beijing International Wind Energy Conference and Exhibition held in Beijing, I produced the fan bearings Invitational Exhibition (Booth No.: EF10), this exhibition is my third time participating Beijing International Wind Energy Conference.
As the world's most authoritative wind energy exhibition, the conference's theme of "from quantitative to qualitative change - the wind energy market new opportunities and new challenges", around the current wind power development facing the market, technology and policy issues such as symposia and fully demonstrated the current global wind power development of the latest results.
National Energy Board Liu Qi, deputy Secretary for was invited to attended the opening ceremony and delivered a speech. Liu Qi, deputy director in his speech that in recent years the rapid development of global wind power, by 2011, the world's wind power installed capacity has reached 238 million kilowatts, becoming an important energy component. China is currently the world's wind power capacity than any other country, is expected to the end of 2012, the national wind power installed capacity will be more than 60 million kilowatts. The party's 18 report, we should vigorously promote ecological civilization construction, and actively develop low-carbon energy industry and new energy, renewable energy, promote energy production and consumption revolution, build a beautiful China. Wind power as an important strategic emerging industries, has a broad development prospects and market space.
