NSK Spherical Roller Bearing Double Row 23140 / 23140K With P5 / P6 Precision
A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment.
Typically these bearings support a rotating shaft in the of the inner ring that may be misaligned in respect to the outer ring.
The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers. Despite what their name may imply, Spherical roller bearings are not truly spherical in shape.
The rolling elements of spherical roller bearings are mainly cylindrical in shape, but have a profile that makes them appear like cylinders that have been slightly over-inflated.

Feature of Spherical roller bearing
1. high temperature applications
2. low revolutions
3. resistant to impact and vibration
4. it has favorable self-alignment function
it can work well when the inner ring axis has a slope to outer ring axis(it usually within 3 °)
5. it main subjected to large radial load and some small axial load
