FAG spindle bearings are super precision single row angular contact ball bearings with solid outer and inner rings

QJ312-MPA-FAG Four Point Contact Ball Bearing 60x130x31mm Closed T - Total width 23FAG Four point contact bearings are similar in their structure to double row angular contact ball bearings, but are considerably narrower in an axial direction due to only one raceway groove. Since the centres of curvature of the arc shaped raceways on the inner ring and outer ring are offset relative to each other, the balls are in contact with the bearing rings at four points under radial load. For this reason, four point contact bearings are only
