The classification of the outer spherical bearing

Insert ball bearing units in accordance with the cooperation with shaft to points can be divided into three categories:
Insert ball bearing units, with the top wire Its code-named: UC200 series, light series), UC300 series product series (heavy), and the deformation UB 200 series (SB), if use environment fit small, usually choose UC200 series, choose UC300 series conversely. Insert ball bearing units are often on the top SiDou is two, the Angle is 120 °, the feature is used when working with shaft top wire to the top on the shaft, then play a fixed effect, but their cooperation environment needs necessary oscillation is small. This kind of outer spherical ball bearing match throughout, is widely used in textile machinery, ceramic machinery and so on various production industry.
Second, insert ball bearing units with taper Its code-named: UK200 series, UK300 series. Such outer spherical ball bearing inner diameter is 1:12 share taper hole, apply to cooperate with tight sleeves when use, this kind of outer spherical ball bearing features as follows: insert ball bearing units can accept than covered wire larger load. Due to its close set set of inner diameter of the same type of insert ball bearing units than covered wire, for example, with the top wire UC209 outer spherical ball bearing inner diameter of 45 mm, instead of the cooperative use of shaft diameter of 45 mm, but if if insert ball bearing units with tapered, can only choose the inner diameter of 45 mm set, and cooperation with 45 mm set set of insert ball bearing units with taper just got UK210 (of course if agree with higher can choose UK310). Thus, acceptable UK210 fit when make a much bigger than UC209.
Third, insert ball bearing units with eccentric sleeve Its code-named: UEL200 series, UEL300 series, SA200 series. Such outer spherical ball bearing on the primary characteristics of bearing must offset degree, and at one end with the same degree of eccentricity of eccentricity With cooperation. Such bearing can also special bearing, due to its top is in agricultural machinery, cutting machine, straw returned machine, thresher, etc.) on apply, such external spherical ball bearing first applied to compare the layout of the strong, offset the layout of the cooperation can be useful to cut a strong beat.
