Although its basic performance is similar to that of deep groove ball bearing, most of the bearings are used in relatively rough machinery, the installation and positioning are not accurate enough, the axis of the shaft and the seat hole is neutral, or the shaft is long and the deflection is large, and the accuracy of the bearing itself is not high enough, and some structures are relatively rough, so the actual performance of the bearing is relatively the same specification Deep groove ball bearings are subject to considerable discount.
