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, enabling the bearing to fit into the corresponding concave spherical surface of the bearing seat, thus having the function of automatic self-aligning. This capability allows the bearing to work within its self-aligning range even when the shaft is deflected due to load or when the installation center line of the shaft and the bearing seat hole is relatively offset, thus 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 primarily used to bear radial and axial combined loads dominated by radial loads, but it is not usually 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 often 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, and more.
• 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 vast and wide-ranging. Their unique design and performance characteristics enable them to play a critical role in numerous industrial fields. Below are the primary application scenarios for outer spherical bearings:

Outer spherical bearings are an essential component in automobile manufacturing, particularly in key parts such as engines, transmissions, rear axles, and steering gears. They are designed to withstand high-speed rotation, high temperature, high pressure, and high-impact loads to ensure optimal vehicle performance and safety.

Outer spherical bearings are widely used in the aviation and aerospace industry for equipment such as aircraft engines, turbochargers, hydraulic pumps, and gyroscopes. These applications have extremely high-performance requirements for bearings that must withstand harsh environments and high-speed rotation loads, and outer spherical bearings are the ideal solution.

Outer spherical bearings are frequently used in agricultural machinery, including tractors, harvesters, seeders, and various other agricultural equipment. This machinery must be able to handle intense vibration, impact, and dust erosion. The durable structure and high resistance of outer spherical bearings guarantee the equipment’s reliability and stability.

Outer spherical bearings are widely used in the industrial equipment sector, including CNC machine tools, robots, wind turbines, and other equipment. This machinery requires bearings that offer high accuracy and reliability. Outer spherical bearings can withstand high-speed rotation and complex loads, ensuring efficient operation and long-term stability.

Outer spherical bearings are used in various other applications, including textile machinery, food processing machinery, printing machinery, logistics, transportation equipment, steel and metallurgical equipment, and so on. These applications need to handle heavy loads and high-speed rotation, and outer spherical bearings offer the characteristics required for optimal performance.
