Spherical roller bearing has two row of spherical rollers,mainly bear radial load,also can withstand axial load in either direction.Its high radial load capacity is especially suitable for heavy work loads or vibration,but can not afford pure axial load.The outer ring raceway of this kind bearing is spherical shape,so spherical roller bearing has good aligning properties,can compensate concertricity error.Generally permissible aligning angle is 1 to 2.5 degrees.
