• Automatic Self-Aligning Abilityings

One of the most notable features of outer spherical bearings is their automatic self-aligning ability. This means that the outer diameter surface of the outer ring is a spherical surface, which allows the bearing to fit into the corresponding concave spherical surface of the bearing seat. As a result, it has the function of automatic self-aligning. Even if 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. This ability helps to avoid the impact of installation errors or shaft deformation on the operation of the bearing.

Outer spherical bearings are mainly used to bear radial and axial combined loads dominated by radial loads. However, 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

Finally, outer spherical bearings have other performance characteristics such as 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 extremely wide-ranging. Due to their unique design and performance characteristics, they play an important role in many different industrial fields.
The following are the primary application scenarios of outer spherical bearings:

• Automotive field: Outer spherical bearings are an essential component in automobile manufacturing. Within the automotive field, they are mainly used in key components such as engines, transmissions, rear axles and steering gears. Moreover, they 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 sectors, outer spherical bearings are widely utilized within equipment such as aircraft engines, turbochargers, hydraulic pumps and gyroscopes. These types of equipment have very high performance demands, where the bearings need 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 are also very popular, such as tractors, harvesters, seeders and other agricultural machinery and equipment. It is imperative that these machines can endure vibration, impact and dust erosion. The heavy-duty structure and high durability of outer spherical bearings can guarantee the stability and reliability of the equipment.
• Industrial Equipment field: In the industrial equipment field, outer spherical bearings are also widely used, such as CNC machine tools, robots, wind turbines and other equipment. These devices have significant 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 machinery.
• Other fields: Outer spherical bearings are also widely used in various other fields, such as textile machinery, food processing machinery, printing machinery, logistics and transportation equipment, steel and metallurgical equipment and other areas. These machines need to be able to endure heavy loads and high-speed rotation, and the properties of outer spherical bearings meet the criteria for these applications.
