Outer spherical bearing is a variant of deep groove ball bearing, characterized by a spherical outer diameter surface on the outer ring, which can be fitted into the corresponding concave spherical surface of the bearing seat for centering.

Outer spherical bearings are mainly composed of inner rings, outer rings, balls, and retainers, which can withstand complex radial and axial loads, as well as rotation and vibration. It is widely used in multiple fields:

1. In the automotive field, outer spherical bearings are mainly used in components such as engines, transmissions, rear axles, and steering systems. They can withstand high-speed rotation, high temperature, high pressure, and high impact loads, ensuring vehicle performance and safety.

2. In the field of aviation and aerospace, outer spherical bearings can withstand extremely harsh environments and high-speed rotating loads in equipment such as aircraft engines, turbochargers, hydraulic pumps, and gyroscopes, ensuring the normal operation of aircraft.

3. In the field of agriculture: In agricultural machinery such as tractors, harvesters, and seeders, outer spherical bearings can withstand vibration, impact, and dust erosion, ensuring the stability and reliability of the equipment.

4. In the field of industrial equipment: In CNC machine tools, robots, wind turbines and other equipment, outer spherical bearings can withstand high-speed rotation and complex loads, ensuring the efficient operation and long-term stability of the equipment.

In addition, outer spherical bearings are preferred for applications that require simple equipment and components, such as agricultural machinery, transportation systems, or construction machinery. In these applications, outer spherical bearings can demonstrate their self-aligning performance, effectively withstand various loads, and ensure the stable operation of equipment. Meanwhile, its excellent sealing performance is also one of the key factors for its application.

In general, outer spherical bearings are a type of bearing widely used in mechanical equipment, with the ability to withstand complex loads and harsh environments, and are important basic components for modern industrial and technological development.
