Spherical rollers have a spherical rolling surface. Bearings with such rollers have self-aligning properties and can withstand large loads. Spherical rollers are divided into asymmetric type and symmetric shape, generally asymmetric large end surface for the spherical surface, symmetric shape of the two end surfaces for the flat end surface.
