NTN KXA055 ultra-thin section type ball bearings are bearings with an extremely thin design. KXA055 is 4-point contact type. When the inner and outer rings are loaded in the radial direction, the ball comes into contact with the inner and outer rings at four points.

KXA055 bearings are generally suitable for two contact points under a simple axial load or a complex load with a larger axial load.
