External spherical ball bearings can be divided into three categories according to the method of cooperation with the shaft:

First, with the top wire outer spherical ball bearing its code for: UC200 series (light series), UC300 series (heavy series), and deformation products UB (SB) 200 series, if the use of the environment is small, usually pick UC200 series, and vice versa, the choice of UC300 series. Usually there are two top filaments on the outer spherical ball bearings, the angle is 120°, its characteristic is to cooperate with the shaft with the top filament to top the shaft, and then play the fixing effect, but its cooperation environment needs to be necessary to oscillate the scale is small. This kind of external spherical ball bearing is relatively widespread, widely used in textile machinery, ceramic machinery and other production industries.


Second, with taper outer spherical ball bearing its code for: UK200 series, UK300 series. This kind of outer spherical ball bearing inner diameter for 1:12 share of the taper bore, use with the tightening sleeve co-operation, this kind of outer spherical ball bearing characteristics for: can accept than with the top wire outer spherical ball bearing greater load. Because of its cooperation with the tightening sleeve with the same type of inner diameter than the top wire outer spherical ball bearings smaller, such as with the top wire outer spherical ball bearings UC209 inner diameter of 45mm, and its cooperation with the use of the shaft diameter of 45mm, and if the assumptions for the replacement of the tapered outer spherical ball bearings, you can only pick the inner diameter of 45mm tightening sleeve, and with 45mm tightening sleeve cooperation with the taper outer spherical ball bearing only the UK The only ball bearing with a tapered outer face that can be used with a 45 mm bushing is the UK210 (of course the UK310 can be used if it is suitable for higher diameters). Thus, UK210 accepts a much larger fit than UC209.


Third, with eccentric sleeve outer spherical ball bearings its code for: UEL200 series, UEL300 series, SA200 series. This kind of outer spherical ball bearing primary characteristic for bearing on one end has a certain degree of eccentricity, have the same degree of eccentricity of the eccentric sleeve and its co-operation. This kind of bearings can also be said to be special bearings, because it is mainly used in agricultural machinery (mowing machine, straw return machine, threshing machine, etc.), this kind of outer spherical ball bearings are mainly used in the layout of the beating is relatively strong, the cooperation of the offset layout can be useful to reduce the strong beating.
