SKF QJ 206 MA–cheap angular contact ball bearings can bear radial load and bidirectional axial load. This single bearing can substitute the angular contact ball bearing of front combination or back combination. It is fit for bearing axial load or resultant load which the radial load is the main load. The main cage of application: copper alloy cut cages. Main usage: airplane jet engine, burning turbine generator. When this kind of bearing carries axial load from any directions, it will form one contact angleα. So ferrule and ball always contact at double-dealing point of any contact line.
