Spherical roller bearings equipped with an outer ring with a spherical raceway surface and an inner ring which holds two rows of barrel shaped rolling elements, NTN spherical roller bearings are able to adjust center alignment to handle inclination of the axle or shaft. There are variety of bearing types that differ according to internal design. Spherical roller bearings include as type equipped with an inner ring with a tapered bore. The bearing can easily be mounted on a shaft by means of an adapter or withdrawal sleeve. The bearing is capable of supporting heavy loads, and is therefore often used in industrial machinery. When heavy axial load is applied to the bearing, the load on rollers of another row is disappeared, and can cause problems. Attention must therefore be paid to operating conditions.
