Spherical bearings, also known as ball joint bearings, are designed to rotate and tilt in multiple axes. This flexibility allows them to compensate for angular misalignment between shafts while ensuring smooth transmission. They are commonly used in transmission systems, including automotive suspension, steering systems, and various mechanical equipment that require axial flexibility.
An inner bearing and an outer casing. The inner bearing is usually spherical in shape with a ball-crown structure to accommodate and support the ends of the shafts. The outer casing is a structure with a spherical groove that secures the inner bearing and provides mounting and connection points.
SPHERICAL BEARINGS SPECIFICATION TABLE 
In summary, a spherical bearing is designed to connect two non-concentric shafts in transmission systems. It compensates for angular misalignment while handling axial loads and lateral forces.

Spherical bearings are commonly used in automotive suspension systems and steering systems. They are used to connect the wheels and suspension system, allowing the wheels to rotate freely and adapt to uneven road surfaces.
In the marine sector, spherical bearings are used to connect propeller shafts and engines, enabling the propellers to rotate and change direction as needed.
Spherical bearings are frequently employed in the joint components of robots. These bearings enable the robot's arms and joints to move in multiple axes.
Spherical bearings are used in many industries because they can handle angular misalignment, making them essential in a wide range of mechanical systems. These are just a few examples of their versatility.
