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.

Lianyungang first for the seizure of high-quality aerospace grade carbon fiber
Recently, high-performance Fibre Product Testing Center Lianyungang province passed the Shanghai Composite Materials Tapered bearing Co., Ltd. (Shanghai Aerospace Composite Materials Technology Center) Service Provider evaluation system assessment, as the company produces aerospace carbon fiber composite materials used in the designated inspection agency. It is reported that this is also the center for the first time assume aerospace grade carbon fiber detection tasks.
Reporters learned that, in order to pass Shanghai company's strict supplier evaluation system assessment, the provincial high-performance Fibre Product Testing Center established a technical group to enhance detection capabilities for technical personnel training, carbon fiber products on foreign standards and technical specifications of special studies. The company provides multiple blind comparison test, the center issued by the company and the test data related to testing organizations at home and abroad compared to fully meet the technical requirements, and ultimately successfully become the company's service provider.
