Ball joint bearing for swivel movements and tilting movements

Spherical plain bearings, also known as ball joint bearings, are components designed for applications that involve swiveling and tilting movements. These bearings consist of an inner ring with a convex spherical surface and an outer ring with a concave spherical surface. This design allows the bearing to handle various types of loads, including radial loads, axial loads, and a combination of both, making it versatile for different mechanical movements. They are suitable in applications where low-speed oscillating movements (angular movements) are required, and they can accommodate tilting motions within a specific angular range, ensuring self-alignment even when there is significant misalignment between the shaft and the housing hole. One of the standout features of these bearings is the self-lubricating capability, thanks to composite materials applied to the outer spherical surface of the inner ring. This ensures smooth operation and durability, especially in environments where maintenance is challenging or where the bearing must function with minimal intervention.
