introduction：Angular contact ball bearingInstallation regulation： 1、The installation and adjustment of low noise angular contact ball bearings can also imitate the grouping method of long-life bearings，The size of fit interference is more consistent，Bearing clearance is also more consistent，And we want the fit interference to be a small value within the possible range，To ensure that the bearing raceway deformation is small，Thus the noise caused by rolling body passing is reduced。 2、The clearance has a great relationship with the noise，The ideal condition is when the imported bearing is in a high temperature state of operation，The clearance value is exactly zero。The methods of determining excessive clearance are：The stationary state displaces the axis axially，The reciprocating range is large，Emit loud and heavy noise during operation。
