  • » Four-point contact ball bearings – two in one

    2015-6-25 · A four-point contact ball bearing can accommodate axial loads in both directions, in combination with radial loads up to a certain level, and provides a very tight axial shaft position tolerance.The bearing also saves space, because it can be seen as the combination of two single row angular contact ball bearings into one.

  • four point contact ball bearing application

    2018-10-29 · The four point contact ball bearing uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that acts to separate the races axially. So the angle of contact on the inner race is the same as that on the outer race. Angular contact bearings better support combined ...

  • Four point contact bearings for greater accuracy |

    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.
