Spherical Plain Bearing
Self-aligning Spherical Bearings were first used by James Nasmyth around 1840 to support line shaft bearings in mills and machine shops.[1] For long shafts it was impossible to accurately align bearings, even if the shaft was perfectly straight. Nasmyth used brass bearing shells between hemispherical brass cups to align the bearings to self-align.
Radial Spherical Plain Bearings GEEM-ES-2RS Series have an inner ring with a sphered convex outside diameter and an outer ring with a correspondingly sphered but concave inside surface.
Their design makes Radial Spherical Bearings GEEM-ES-2RS Series particularly suitable for bearing arrangements where alignment movements between shaft and housing have to be accommodated, or where oscillating or recurrent tilting or slewing movements must be possible at relatively slow sliding speeds, often accompanied with heavy loads.

Spherical Bearings GEEM-ES-2RS Series is a bearing that permits angular rotation about a central point in two orthogonal directions (usually within a specified angular limit based on the bearing geometry). Typically these bearings support a rotating shaft in the [bore] of the inner ring that must move not only rotationally, but also at an angle.
