Self-aligning roller bearing also has 2 rows of rolls, and only 1 sphere raceway in the outer ring.
These bearings's Self-aligning performance also very good, can compensate the coaxial tolerance of error.
The inside and outer relative gradient must not exceed about **2.5 degrees.
Self-aligning roller bearing has a very good impact resistant capability. Normally this type of bearings are work in low rotationl speed.

Self-aligning ball bearing & Self-aligning roller bearing's inside hole cylindrical and conical two kinds.
The taper of inner hole is 1:*2 or 1:*0.
