QJ311-XL-MPA-C3-FAG Four Point Contact Ball Bearing 55x120x29mm Shields Synchronous Timing Belts are ableFAG 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
