What's axial needle bearings or axial needle roller bearings?

"Axial Needle Bearing" and "Axial Needle Roller Bearing" are just two variations of a type of bearing that the bearing industry typically calls "Roller Thrust Bearings" or "Cylindrical Roller Thrust Bearings." In all of these cases, the bearing is designed to support high axial loads as compared to radial ball bearings.

Generally, roller thrust bearings consist of two washers and rolling elements which, in this case, are rollers as opposed to thrust ball bearings which use balls as their rolling elements. While ball thrust bearings sometimes use groves in the raceways, typically roller thrust bearings use retainers to ensure proper spacing and orientation.

A cylindrical roller thrust bearing is a particular type of roller bearing. Like other roller bearings, they permit rotation between parts, but they are designed to support a high axial load while doing this . Higher speed applications require oil lubrication. Generally, they are composed of two washers and the cylindrical roller elements which are typically caged. As opposed to roller thrust bearings, ball thrust bearings can generally operate at higher speeds but at lower loads.
