The characteristics of outer spherical bearings can be summarized as follows:

• Automatic self-aligning ability: The notable feature of outer spherical bearings is that the outer diameter surface of the outer ring is a spherical surface, which enables the bearing to fit into the corresponding concave spherical surface of the bearing seat, thus having the function of automatic self-aligning. When the shaft is deflected due to load or the installation center line of the shaft and the bearing seat hole is relatively offset, the bearing can still work within its self-aligning range, avoiding the impact of installation errors or shaft deformation on the operation of the bearing.
• Bearing radial and axial combined loads: outer spherical bearings are mainly used to bear radial and axial combined loads dominated by radial loads, but it is usually not recommended to bear axial loads alone during design.
• Double-layer seal design: outer spherical bearings generally have a double-layer seal design, mainly because they are usually used in harsh operating environments, such as agricultural machinery bearings. The double-layer seal ensures that dust is not easy to enter the inside of its channel, thereby extending the service life of the bearing.
• Structural features: The inner diameter of the outer spherical bearing is a tapered inner hole with a ratio of 1:12, and it needs to cooperate with a tight sleeve when used. There are outer spherical ball bearings with top screws and eccentric sleeves, and their application scenarios and performance characteristics are slightly different.
• Wide range of applications: outer spherical bearings are widely used in the industrial field, such as large machinery and equipment, heavy machinery, construction machinery, agricultural machinery, transmission equipment, mining machinery, etc.
• Other performance: outer spherical bearings have the characteristics of large load capacity, long service life, easy installation, and prevention of outer ring rotation. In harsh working environments, such as high temperature, heavy load, vibration and other conditions, outer spherical bearings can still maintain a stable working state.

The application scenarios of outer spherical bearings are wide, and their unique design and performance characteristics make them play an important role in many different industrial fields. The following are the main application scenarios of outer spherical bearings:

• Automotive field: Outer spherical bearings are particularly widely used in the automotive field and are one of the indispensable components in automobile manufacturing. They are mainly used in key components such as engines, transmissions, rear axles and steering gears, and can withstand high-speed rotation, high temperature, high pressure and high impact loads to ensure the performance and safety of vehicles.
• Aviation and aerospace fields: In the aviation and aerospace fields, outer spherical bearings are widely used in equipment such as aircraft engines, turbochargers, hydraulic pumps and gyroscopes. These equipment have extremely high performance requirements for bearings and need to be able to withstand extremely harsh environments and high-speed rotation loads. The excellent performance of outer spherical bearings just meets these requirements.
• Agricultural field: In agricultural machinery, outer spherical bearings have also been widely used, such as tractors, harvesters, seeders and other agricultural machinery and equipment. These equipment need to be able to withstand vibration, impact and dust erosion. The heavy-duty structure and high durability of outer spherical bearings can ensure the stability and reliability of the equipment.
• Industrial equipment field: In the field of industrial equipment, outer spherical bearings are also widely used, such as CNC machine tools, robots, wind turbines and other equipment. These equipment have high requirements for the accuracy and reliability of bearings. Outer spherical bearings can withstand high-speed rotation and complex loads to ensure the efficient operation and long-term stability of the equipment.
• Other fields: Outer spherical bearings are also widely used in textile machinery, food processing machinery, printing machinery, logistics and transportation equipment, steel and metallurgical equipment and other fields. These equipment need to be able to withstand heavy loads and high-speed rotation, and the characteristics of outer spherical bearings just meet these requirements.
