Difference between self-aligning roller bearing post-code K and K30

Self-aligning roller bearing is a non-separable bearing, mainly composed of outer ring, inner ring, cage and drum-shaped roller with spherical raceway.
The rollers with symmetrical drum design are used to compensate for shaft bending deformation and misalignment of the mating surface through free adjustment in the outer ring raceway. The drum rollers are generally arranged symmetrically,
Spherical Roller Bearings 
Therefore, it can well withstand the axial and radial load forces from both directions.
Self-aligning roller bearings have large two-way bearing capacity and the ability to compensate for misalignment. They are widely used in the application design of mechanical products in various industries.
Self-aligning roller bearing can also be divided into cylindrical inner hole and conical inner hole. Self-aligning roller bearing with a taper of 1:12 and a post-code of K (such as 153000 or 113000) and 1:30 self-aligning roller bearing with a post-code of K30.
When the self-aligning roller bearing is measured, the ratio of the difference between the size and diameter of the tapered hole and the thickness of the bearing is usually referred to as the post-code.
K represents 1:12 and K30 represents 1:30.
