SKF Self aligning ball bearing with polyamide cage 12mm inside x 37mm outside x 12mm wide, also known as 1301ETN9, 1301TV, 1301TVH, 1301TN
The self-aligning ball bearing was invented by SKF. It has two rows of balls and a common sphered raceway in the outer ring. The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing.
The design of self-aligning ball bearings is such that angular misalignment between the outer and the inner rings can be accommodated without any negative effect on bearing performance.
