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.

Tricyclic Group invested 570 million acquisition of the Polish manufacturer of bearings
Gasgoo News According to Reuters, China tricyclic group will spend 570 million yuan acquisition of Polish manufacturer of bearings FLT Krasnik, this will be the Chinese enterprises in Poland, by far the largest investment.
Current FLT Krasnik shares 89% by the Polish National Industrial Development Agency ARP hold. ARP President Wojciech Dabrowski and several Krasnik executives visited the tricyclic group last month, the two sides to commence merger negotiations. The ring will be $ 93 million to buy Krasnik, about 572 million yuan.
Informed sources said that last year, Chinese Premier Wen Jiabao's visit to Poland before, set the goal of doubling trade wave, the transaction is the result of consultations during the visit.
Swiss famous bearing manufacturer RKB Group is D & B rating certificate
Swiss famous Precision bearing manufacturer RKB Group is D & B Bai-linked certificates bearing Reuters D & B rating certificate is a commercial quality certification, on behalf of the company's reliability and stability. In Switzerland, only 2% of the company to meet the D & B rating certificate requirements. The company must obtain this certificate is D & B division in the lowest risk category up to 12 months and above. This certification is granted to indicate RKB Group's business situation is very stable, is their trusted business partner
Aligning ball bearing outer ring raceway spherical, aligning performance, it can automatically adjust the shaft or housing deflection or misalignment of axis errors caused.
Aligning ball bearings mainly take radial load, but can withstand axial load is small. Axis (shell) limit the axial displacement within the limits of the clearance, with self-aligning performance, allowing the inner, peripheral conditions relatively little inclination to work, for bearing seat hole can not be strictly guaranteed concentricity of the parts. Aligning ball bearing outer ring raceway is processed into spherical shape, there are two inner raceway groove double row ball bearings, aligning performance. It is mainly used to bear radial load, radial load, but also can withstand a small amount of axial load, but generally can not bear the pure axial load, the speed limit than the deep groove ball bearings. These bearings are used for the load prone to bending under the double bearing shaft, and a dual bearing seat hole can not guarantee strict concentricity of the parts inside, but the inner ring and outer ring centerline centerline relative inclination of not more than three degrees.
