4 point ball bearings handle two directional axial loading, for example in power transmission. The balls are contained in inner and outer raceways. Performance depends upon the shape of the raceways and the four points at which the balls are in contact with them. Because of the shape of the raceways the bearings are often referred to as "Gothic Arch bearings".

Gothic Arch analysis automatically calculates a full set of parameters for a circular ball bearing in contact with a measured raceway profile, including contact angles and center pitch making it possible to predict performance.
