Product Description

 

Spherical seated bearings, also known as spherical plain bearings or spherical rod ends, are essential components in mechanical systems where rotational or oscillating movements occur. These bearings provide flexibility in accommodating misalignment between connected components, making them ideal for applications where shafts or rods may not be perfectly aligned.

Unlike traditional ball bearings that primarily handle axial and radial loads, spherical seated bearings excel in situations requiring both rotational movement and misalignment compensation. They consist of an inner ring with a convex spherical interior and an outer ring with a corresponding concave spherical exterior. This design allows the bearing to articulate in multiple directions, providing smooth movement and reducing friction even under challenging conditions.
