introduction:For self-aligning bearings[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。]As for,When loading the bearing with shaft into the housing shaft hole,The intermediate mounting ring prevents the outer ring from tilting and rotating。What should be remembered is this,Some sizes of self-aligning ball bearings have the ball protruding from the side of the bearing,So the middle mounting ring should be recessed,Prevent damage to ball。A good deal of
