Classification Of Outer Spherical Bearings

The outer spherical bearings can be divided into three main categories according to the cooperative method with the shaft:

First, with the top wire outer spherical ball bearing its code: UC200 series (light series), UC300 series (heavy-duty series), and deformation product UB (SB) 200 series, if the use of the environment fit is small, usually choose the UC200 series, on the other hand, the UC300 series. Usually the outer spherical ball bearing on the top wire are two, its angle is 120 degrees, its characteristic is to cooperate with the shaft is to use the top wire to top on the shaft, and then play a fixed effect, but the environmental needs of its cooperation need to oscillate small scale. This kind of outer spherical bearing comparison throughout, widely used in textile machinery, ceramic machinery and other production jobs.

Second, with cone outer spherical ball bearing its code name: UK200 series, UK300 series. This kind of outer spherical ball bearing internal diameter of 1:12 share of the cone inner hole, when used with the tight set of cooperation, the characteristics of this kind of outer spherical ball bearing is: can accept a larger load than the outer spherical bearing with the top wire. Since the inner diameter of the same type of tight set with it is smaller than the outer spherical bearing with the top wire, For example, with the top silk outer spherical ball bearing UC209 internal diameter of 45mm, with its cooperation with the use of the shaft diameter of 45mm, and if you replace with a taper outer spherical ball bearing, you can only select the inner diameter of 45mm tight set, and with 45mm of the tight set of the tie-cone outer spherical ball bearing simply has 210 (if the united states of course) can be higher. As a result, the UK210 accepts a much bigger fit than UC209.

Third, with eccentric sets of outer spherical ball bearings, its code name: UEL200 series, UEL300 series, SA200 series. The primary feature of this kind of outer spherical bearing is that the upper end of the bearing has a certain degree of eccentricity, there is the same degree of eccentricity of the pain set with its cooperation. Such bearings can also be said to be special bearings, because it is the first in the agricultural machinery (cutting machine, straw machine, granulation machine, etc.) on the use of such outer spherical bearings first use in the beating ratio of strong layout, the cooperation of the pain layout can be useful to reduce the strong beat.
