NTN NK20/20R bearing

20x28x20

Over time, the main improvements have come from sealing materials rather than geometrical differences. Bearing Production. Bearing production in volumes is an almost entirely automated process and was pioneered by the Japanese. The big four (SKF, NTN, NSK and FAG) produce thousands of bearings every second with little human intervention.
