Spherical roller bearings have two rows of rollers, and are able to accommodate large radial loads and take some axial loads in either direction. These double-row spherical roller bearings are suitable for vibration or heavy load applications, but can not handle pure axial loads.
To mount a spherical roller bearing having a tapered bore with a taper of either 1:12 (designation suffix K, 153000 series / 113000 series) or 1:30 (designation suffix K30), the inner ring can be moved in a radial direction to adjust the radial internal clearance of the bearing.
The code on the bearing may be varied even for the same structure.
