Self aligning ball bearing with polyamide cage & C3 clearance 45mm inside x 85mm outside x 19mm wide, also known as 1209ETN9C3, 1209TVC3, 1209TVHC3, 1209TNC3
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.
