It can bear radial load and bidirectional axial load. A single bearing can replace the angular contact ball bearing of front combination or back combination. It is suitable for bearing pure axial load or synthetic load with large axial load component. This type of bearing can withstand any direction. One of the contact angles can be formed when there is an axial load, so the ferrule and the ball are always in contact with three points on both sides of any contact line.
Four point contact ball bearings
Main uses: aircraft jet engines, gas turbines.
