NTN KYA055 ultra-thin section type ball bearings are bearings with an extremely thin design.

KYA055 is angular type, which have a straight line that runs through the point where each ball contacts the inner and outer rings at two points at 30° with respect to the radial direction. KYA055 bearings can receivea a unidirectional axial load or a complex load of radial load and axial load. The ability to include an increased number of balls increases the load capacity of the bearing.

NTN KYA055 bearings are normally used in pairs for applications where it is necessary to control the axial movement via axial internal clearance or preload.
