This complex bearing is comprised of a needle roller bearing for supporting radial load, a ball bearing for supporting comparatively small axial load and machined inner and outer rings which are all assembled integrally. Both angular contact ball bearing and three-point contact ball bearing are available to support the axial load.

• The complex needle roller bearings (NKIA Series) use an angular contact ball bearing as the thrust bearing to support a one-directional axial load.

• The complex needle roller bearings (NKIB Series) use a three-point contact ball bearing as the thrust bearing to support a double-directional axial load in addition the position in axial direction can be fixed.
