The Type X, or 4-point contact, ball bearing is ideal for moment loading. Type X bearings are designed with gothic arch raceways creating 4 contact points between the balls and the raceways.

This design is excellent for moment loading and reversing axial loading. The Type X bearing can be used for other light loading conditions, but is not recommended in place of the Type C or Type A bearing for pure radial or axial loads.
