Do you know the classification of radial insert ball bearing?

The radial insert ball bearing can be divided into three categories according to the cooperation method with the shaft:
1. The radial insert ball bearing with the top wire is coded as: UC200 series (light series), UC300 series (heavy series), and deformation product UB (SB) 200 series. If the application environment is small, the UC200 series is usually selected. Then choose UC300 series. Usually, there are two top wires on the outer spherical ball bearing, and the angle is 120°. The characteristic is that when the shaft cooperates with the shaft, the top wire is used to top the shaft, and then the fixing effect is achieved, but the cooperation is achieved. Environmental needs are necessary to oscillate on a small scale. This kind of radial insert ball bearing is widely used in various production jobs such as textile machinery and ceramic machinery.

2.The tapered radial insert ball bearing code: UK200 series, UK300 series. This kind of outer spherical ball bearing has a 1:12 share taper inner hole. It should be used in conjunction with the tightening sleeve. The characteristics of this kind of radial insert ball bearing are: it can accept larger than the radial insert ball bearing. load. Because the inner diameter of the same type of sleeve is smaller than that of the radial insert ball bearing, the inner diameter of the radial insert ball bearing UC209 is 45mm, and the diameter of the shaft used in cooperation with it is 45mm. If you change to a tapered radial insert ball bearing, you can only select the adapter sleeve with an inner diameter of 45mm, and the tapered radial insert ball bearing with the 45mm adapter sleeve is only the UK210 (of course, if the fit is higher, you can pick UK310). As a result, the acceptance of the UK210 is much larger than that of the UC209.

3.With eccentric radial insert ball bearing The code is: UEL200 series, UEL300 series, SA200 series. The first characteristic of this kind of radial insert ball bearing is that the upper end of the bearing has a certain degree of partial pain, and the partial pain set with the same degree of partial pain cooperates with it. Such bearings can also be said to be radial insert ball bearing. Since they are mainly used on agricultural machinery (harvesters, straw returning machines, threshers, etc.), such as radial insert ball bearing is mainly used in the layout where the beating is strong, and the pain is too The cooperation of the layout can be useful to cut the strong beat.
