The outer spherical ball bearing is actually a modification of the deep groove ball bearing. Its characteristic is that the outer diameter surface of its outer ring is spherical, which can be fitted into the corresponding concave spherical surface of the bearing seat to play the role of self-alignment. Outer spherical bearings are mainly used to bear combined radial and axial loads, mainly radial loads, and are generally not suitable for bearing axial loads alone.


115The outer spherical bearing has a large radial load carrying capacity.

It consists of an inner ring, an outer ring, rolling elements and a cage, in which the rolling elements are spherical, and the surface of the inner ring and the outer ring are concave and convex corresponding to each other, so that the axial load bearing capacity is relatively small. Therefore, the outer spherical bearing is suitable for large-scale mechanical equipment, such as heavy machinery, construction machinery, etc., and can withstand greater pressure to ensure the normal operation of the equipment.


Secondly, the outer spherical bearing has better self-aligning performance, and can automatically adjust the inclination of the bearing and the shaft. This feature enables the outer spherical bearing to maintain a stable working state under different working conditions, reduce the deviation and vibration generated during the operation of the equipment, and improve the working efficiency and reliability of the equipment.


The outer spherical bearing also has better sealing performance.

There are seals inside the bearing, which can effectively prevent dust, pollutants and liquids from entering the inside of the bearing, thereby reducing the wear and failure of the bearing. This feature enables the outer spherical bearing to adapt to harsh working environments, such as mining, metallurgy and other heavy industry fields, and can ensure the long-term operation and stable operation of the equipment.


013Insert spherical bearings are used in a wide range of fields:

In the field of mechanical engineering, outer spherical bearings are widely used in large heavy-duty equipment such as lifting machinery, construction machinery, and metallurgical equipment; in the field of agricultural machinery, outer spherical bearings are widely used in agricultural machinery such as tractors, harvesters, and seeders. .

In addition, the outer spherical bearing can also be used in transmission equipment, mining machinery and other fields.


The importance of spherical bearings in industrial production cannot be ignored. It can not only work normally under heavy load, high temperature, high speed and other harsh working environments, but also provide stable and reliable support and friction reduction.
