Northwest bearing announcement, the company received the National Defense Industry Bureau issued a " weapons and equipment research and production license" recently , which conical bearing marks the strategic transformation of the company into the military field has been substantial progress. Boosted by the news in early trading today , the company stock was trading.
Our company is a large, large petrochemical machinery, metallurgical and mining machinery, engineering machinery bearing enterprise , the company is increasing research and development of high-end products bearing . Twelve new company bearing rail Institute , Institute of sealed bearing Institute and other military equipment , in-depth research and development for different research directions.
Li Shuming , general manager , said the focus of the company's future business is expanding core business.  also said the company will be railway wagons bearing , military bearing , cement machinery bearing development , vigorously develop new industries to support national advocacy bearing market , cultivate new pillar products to broaden the company's product markets

slewing ringthin all because of the problems caused by oil and will no longer exist

Using magnetic bearings , all because of the problems caused by oil and will no longer exist . Frequency magnetic levitation centrifuges in one fell swoop to overcome the traditional mechanical bearing centrifuge limited energy efficiency , noise, starting current, higher maintenance costs of a series of drawbacks , is a more energy- efficient central air-conditioning products.
According to reports, Gree frequency magnetic levitation centrifugal refrigeration compressor applications of magnetic bearing technology, the compressor is running without oil , greatly reduce mechanical losses , thus significantly improve the energy efficiency of the unit , this is an effective way to achieve energy centrifuges . According to vice president of Gree Electric Appliances , chief engineer Huang introduced the development of magnetic bearing centrifugal compressor technology to use, difficult, high threshold . In order to overcome technical difficulties , Gree R & D department spent nearly four years , has experienced numerous failures , and finally successfully developed a maglev centrifugal compressor , with the compressor unit Gree significantly improve energy efficiency , the effective realization of centrifuges to achieve energy efficiency, conditioned life.
The Gree independent research and development ' maglev frequency centrifugal chillers ' , with completely independent intellectual property rights , at home and abroad to fill the large compressor cooling capacity maglev research and product gaps
