SKF Self aligning ball bearing with polyamide cage & tapered bore 40mm inside x 80mm outside x 18mm wide, also known as 1208EKTN9, 1208KTV, 1208KTVH, 1208KTN
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.
