Needle roller bearings with thrust ball or roller bearings

There are different types of complex needle roller bearings that can be classified as follows:

• Needle roller bearing with thrust bearing: this complex bearing is comprised of a needle roller bearing for supporting radial load and a thrust bearing for supporting axial load which are assembled integrally. Both thrust ball bearing and thrust roller bearing type are available to support axial load.
• Needle roller bearing with angular contact ball bearing, needle roller bearing with three-point contact ball bearing: 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.
• Needle roller bearing with double thrust roller bearing: this is a complex bearing wherein a thrust needle roller bearing or a thrust cylindrical roller bearing intends

to support an axial load is configured at the double sides of a radial needle roller bearing for supporting radial load. This complex bearing can withstand large axial loads from both sides and is designed to support machine tool precision ball screws.
