Increase scientific and technological research and development efforts
Northwest bearing to the production of large , large, extra large bearing products as a basis , after many years of accumulation, reached a certain scale of production, has been listed as one of six large enterprises stalls bearing industry . The company has an important national enterprise technology center , the National and Local Joint Thin section bearing Engineering Laboratory , postdoctoral research station, established a technology center at the core and relying on technological innovation system , with proprietary technologies and technical know-how a number of independent intellectual property rights. Companies Famous Chinese Trademark trademark brand , brand awareness and market influence in the Rolling mill bearings industry at a higher position. However, due to a shortage of funds in recent years , lack of technological inputs , equipment becomes obsolete influence companies to improve competitiveness and to develop high-end products "bottleneck ." Compared with the same industry advanced enterprises , and gradually widening the gap , in terms of sales revenue in the industry at around 30 , a larger decline .
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.
