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.

NTN Bearing deep groove ball bearings with sealing material performancerequirements'
Kunshan bearing: NTN bearings factors mainly refers to the installation and adjustment, use and maintenance, repair and other maintenance meets the technical requirements. According deep groove ball bearing installation, use, maintenance, maintenance of the technical requirements for operation of the bearings to bear the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal immediately find reasons to adjust bring it back to normal.
Deep groove ball tapered bearing seal data is to ensure effective functioning of the primary sealing element selection sealing materials, sealing element according to the first if the work, such as the use of temperature, operating pressure, by the use of working media and sports style pattern and so on. The sealing of the basic request the following information:
1. NTN Bearing wear, do not corrode the metal;
2 oxygen resistance and good resistance to aging, durable;
3.Bearing low temperature flexibility, high temperature does not synthesized, softening, hardening is not low;
4. NTN Bearing with working media, no swelling, synthesis, hardening;
5 elasticity and hardness properly, tighten forever deformation;
NTN Bearing materials metallurgical quality deep groove ball bearing affect early failure of the main factors. As metallurgical techniques (such as bearing steel vacuum degassing, etc.) progress, improve the quality of raw materials. Raw material quality factors in bearing failure analysis in the proportion has decreased significantly, but it is still bearing failure is one of the main factors. Appropriateness of the selection is still bearing failure analysis must be considered.

SQGTC increase the variety of glass bearing inspection project
National security glass and quartz glass Product Quality Supervision and Inspection Center (SQGTC), recently by the relevant national authority, after re-evaluation, an increase of more glass products bearing inspection items.
National security glass and quartz glass products belonging to the State Quality Supervision and Inspection Center of Quality Supervision, Inspection and Quarantine authorized China National Testing Center National Accreditation tapered bearing accredited national testing center. The re-evaluation, the center for the seizure of the glass product range includes: coated glass, hollow glass, float glass, sheet glass, tinted glass, patterned glass, laminated glass, tempered and semi-tempered glass, fire-proof glass, automotive safety glass , aircraft glazing, ship glass, quartz glass, and cast stone products.
National security glass and quartz glass product quality supervision and inspection center dedicated to glass, quartz glass and other products, testing, testing technology research and related standards revision work. Center in 1990, passed the U.S. official agencies AAMVA (American Association of Motor Vehicle Administration) review, as its foreign inspection AIs can be carried out to the American National Standards-based automotive safety glass DOT certification testing.
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.
