China UC203-11 Insert ball bearing

Inche size UC 203-11 Insert ball bearing, bore size 5/8 inch, 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. For example, the insert ball bearing with jackscrew is applied to the through shaft with large rigidity difference and deflection. Both sides of the bearing are provided with sealing rings, which can prevent the invasion of dirt and have been filled before leaving the factory.

The code of tapered bore pillow block ball bearing is UK200 series and UK300 series. The inner diameter of this kind of spherical ball bearing is 1:12 taper bore, which should be used in cooperation with the tightening sleeve. The characteristics of this kind of spherical ball bearing are: it can accept more load than the insert ball bearing with jackscrew. For example, the inner diameter of uc209 is 45mm, and the diameter of the shaft used in cooperation with uc209 is 45mm, But if we change it into the tapered insert  ball bearing, we can only choose the tight set with an inner diameter of 45mm, and the tapered outer insert ball bearing with 45mm tight set only has uk210 (of course, if it fits higher, we can choose uk310). As a result, uk210's acceptance of the fit should be much greater than uc209's.
