Original NSK 2213 ETN9 65x120x31mm Self Aligning Ball Bearing

A self-aligning ball bearing is equipped with spherical balls between the inner ring of two raceways and the outer ring, whose raceway is spherical.
The curvature center of the outer ring raceway surface is consistent with the bearing center, so it has the same centering function as the self-aligning ball bearing. When the shaft or housing is deflected, it can be adjusted automatically without increasing the bearing burden. Spherical roller bearings can carry radial load and axial load in two directions. Large radial load capacity, suitable for heavy load and shock load. Bearings whose inner diameter is a tapered bore can be directly installed. Or use an adapter sleeve or a disassembly tube to install it on the cylindrical shaft. The cage uses a steel stamping cage, polyamide forming cage, and copper alloy car cage.
