Where is the outside ball bearing used?

Author:


The outer ball bearing, also known as the outer ball bearing, is a special type of bearing, whose outer diameter surface is spherical and has self-aligning performance. This kind of bearing is mainly suitable for bearing the combined radial and axial load, but generally it is not suitable to bear the axial load alone.

Outer spherical bearings are widely used in many fields, such as industrial machinery, fans, light-load transmission and so on. For example, the outer spherical ball bearing with top wire is suitable for the through shaft with large stiffness difference deflection, which can strictly prevent the invasion of dirt, the factory has been filled with appropriate amount of lubricant, and there is no need to clean and add lubricant before installation. In addition, the spherical ball bearing outside the tapered hole can be installed directly on the tapered shaft or on the shaftless shoulder smooth shaft with the help of a fastening bushing, and the bearing clearance can be fine-adjusted.

Specifically, outer spherical bearings are preferred for situations where simple equipment and parts are required, such as agricultural machinery, transportation systems or construction machinery. In these applications, the outer spherical bearing can give full play to its self-aligning performance, effectively withstand various loads and ensure the stable operation of the equipment.

At the same time, the sealing performance of the outer spherical bearing is also one of the key factors in its application. According to different application scenarios, different types of seal configurations can be selected, such as nitrile rubber single lip seal, single lip seal with dust cover, three-layer lip seal, L4 labyrinth seal, etc., in order to meet different pollution levels and speed requirements.

External ball bearings are widely used in many fields, and their unique self-aligning performance and good sealing performance make them an ideal choice for bearing combined radial and axial loads.
