SKF Self aligning ball bearing with polyamide cage & C3 clearance 20mm inside x 52mm outside x 15mm wide, also known as 1304ETN9C3, 1304TVC3, 1304TVHC3, 1304TNC3
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.
