Structural position and use environment of Spherical Bearings

- Mar 15, 2019-

The Spherical Bearing is the outer spherical bearing we usually call. The reason why it is called the ball bearing is because it belongs to the deep groove ball bearing, and the rolling element inside is the steel ball. The outer spherical ball bearing is more convenient to use than the general deep groove ball bearing. Its main features are simple loading and unloading, and can be adjusted. The standard tolerance of the outer spherical ball bearing is: internal plus external subtraction, and the inner diameter adopts tolerance to ensure the cooperation with the shaft. Lightweight.

Each set of outer spherical ball bearings is not used separately. It must be fitted to the inner part of the bearing housing. The outer spherical bearing housing has various shapes and is suitable for various structural positions when fully integrated. The outer spherical ball bearing has a double seal compared to other ordinary bearings, because the general environmental conditions of the outer spherical ball bearing are harsh, especially for agricultural machinery bearings, and the double seal ensures that dust does not easily enter the interior of the channel. In the past two years, some companies have developed a three-lip sealed outer spherical bearing to greatly enhance the dustproof capacity and extend the service life of the bearing.


Spherical bearings must be used in conjunction with the adapter sleeve to withstand greater loads than the outer spherical ball bearings. Because the inner diameter of the same type of adapter is smaller than that of the outer spherical ball bearing, for example, the outer diameter of the outer spherical ball bearing UC209 is 45mm, and the diameter of the shaft used with it is 45mm, and if If it is replaced by a tapered outer spherical ball bearing, only the adapter sleeve with an inner diameter of 45 mm can be selected.
