Spherical Roller Bearings has double row rollers, the outer ring has one common spherical raceway, and the inner ring has two raceways, which are inclined at an angle relative to the bearing axis. This ingenious structure makes it have automatic centering performance, so it is not easy to be affected by the error or shaft bending caused by the angle between the shaft and the bearing housing seat. It is suitable for the occasion of angle error caused by installation error or shaft deflection. In addition to bearing radial load, the bearing can also bear two-way axial load.

Spherical Roller Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection and with relatively heavy radial loads and some axial loads in either direction. Spherical Roller Bearings are designed to be more robust by carry heavier loads but at lower maximum speeds. These bearings have barrel-shaped rollers between the inner ring, which has two raceways, and the outer ring which has one spherical raceway. '
Features of Spherical Roller Bearings
1). High Precision and Long Lifespan
2). Able to accommodate both radial and thrust loads
3). Less coefficient of friction
4). Available in arrange of Polyamide, steel and brass cage assembles
5). Open and sealed versions available
Industrial Applications of Spherical Roller Bearings
Spherical Roller Bearings are non - separable double - row radial bearings.
Both rows of barrel shaped rollers rotate, in parallel, within the spherical outer ring. This allows excellent alignment compensation, caused by machining and mounting errors, between the shaft and housing.
Spherical roller bearings are typical bearings for heavy machinery and mining.
