Do you know the structure of pillow ball bearing?

Main features and applications of pillow ball bearing:
1. The pillow ball bearing with seat consists of an outer spherical ball bearing and an outer spherical bearing seat. When in use, there is no need to design the bearing box separately, so the size is small, the structure is simple, and it can be directly installed on the design part of the host with bolts, which is extremely convenient to use.
2. The bearing housing has an integral structure with large carrying capacity and good rigidity. The bearing and the bearing housing can be interchanged, that is, the same bearing housing can be installed with various types of bearings; similarly, the same bearing can be equipped with various types of bearing housings.

3. The structure of the pillow ball bearing with seat has an automatic centering function, which is especially suitable for working under the condition that it is difficult to ensure the accurate position of the bearing axis (such as a flexible long shaft).
4. The pillow ball bearing is generally pre-filled with grease and adopts a double-sealed type, especially in the occasion of dust, cement, and corrosive media, which is most beneficial to the work group of the host.

5. The inner hole of the pillow ball bearing adopts the "+" tolerance, and forms a clearance fit with the shaft (except for the adapter sleeve). The bearing is fixed by the top wire, eccentric sleeve or adapter sleeve on the inner ring. It is fixed on the shaft, which not only facilitates the installation and removal of the pulling wire, but also reduces the requirements on the machining accuracy of the shaft. It is very convenient to replace the bearing when the main engine is repaired.

Because the pillow ball bearing has the above-mentioned main characteristics and characteristics, it can ensure its stable and reliable operation in harsh environments. Therefore, as the general parts of the main engine, the outer spherical ball bearing with seat is widely used in agricultural machinery, textiles, light industry, metallurgy, coal, chemical industry, forestry, tobacco, packaging, food, printing and other industries.
