CAI轴承一般为电机级轴承，最常用的轴承公差精度见附表所示。
CAI bearings are of motor class bearings and the common tolerance is shown on the attached data sheet.
可提供普通公差公差无后缀的角接触球轴承uo或者UA通用设计型，并且，也能提供P 5级别公差后缀p5。
Angular contact ball bearings of universal design UO or UA are supplied with normal tolerances no suffix for the tolerance and, upon request, with tolerance class P5 suffix P5.
