introduction：IKOAngular contact ball bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Three factors in relation to life，The quality of the bearing itself。two，Use environment。three，Installation method。 These changes will have small bearing damage resulting in performance，Depends on the specific requirements of the bearing。Tracks can be irregular distributions of depression，May also be

introduction：The transverse thickness of the strip is different（That is, the change in the shape of the section）The change of the shape of the roll seam is caused by the change of the shape of the roll seam。The factors that affect the shape of the roll gap are： 1） Elastic bending deformation of roll。It makes the middle size of the roll gap larger than the side size，The edge of the strip produces convexity，Strip edge thinning。Greater rolling pressure，The greater the elastic bending deformation of the roll；The larger the diameter of the roll，The more rigid it is，The elastic bending deformation of the roll is smaller。 2） Thermal expansion of the roll。Heat generated by deformation of rolled parts during rolling、
