The self aligning roller bearing / spherical roller bearing has two row roller, one common spherical raceway of outer ring, two raceway in the inner ring so that the structure makes it self aligning performance and not easier susceptible to the error of shaft, bearing housing angle or shaft bending effect.
It suitable for installation of the parts which has errors caused by shaft deflection and installing.
In addition, the self-aligning roller bearing bears radial load and axial load.
Inner diameter: >16mm
Outer diameter: >51mm
E.g. 21304CCK+H304 Model – 17*32*52*15
The principle of the structure characteristics is similar. The only difference is that the rolling element is a spherical roller so that self-aligning roller bearing carries larger capacity.
In case the same of the capacity and speed requirement; both bearings can be used as a replacement.
