Accuracy class editor angular contact ball bearings, including dimensional tolerances and precision grade rotation accuracy. From low to high accuracy is expressed as P0 (Normal), P6 (P6X), P5, P4, P2. In addition, European and American brands also use the P3, P7, P9, said accuracy class, P3 is equivalent to ISO and JIS standards P6 level, P7 P4 level equivalent Kengzi circuit board equipment bearings, P9 is equivalent to P2 level. Single row angular contact ball bearings Single row angular contact ball bearings can withstand axial load bearing one direction, in the radial load, will cause additional axial force must be applied to the corresponding reverse load bearing freshwater circuit board equipment, so The kinds of bearings are generally used in pairs. Double row angular contact ball bearings can withstand greater radial load mainly radial and axial joint load and moment load, it can limit the bi-axial displacement of shaft or housing, the contact angle of 30 degrees. Longgang circuit board equipment bearings, bearings, bearing along GF electromechanical provided by Shenzhen-GF bearing Electrical Co., Ltd..
