Q20. What is an Axial Needle Bearing or Axial Needle Roller Bearing?

"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 (i.e. loads parallel to the shaft) as compared to radial ball bearings

Generally, roller thrust bearings (a.k.a. Axial Needle Bearings or Axial Needle Roller Bearings) consist of two washers (raceways) and rolling elements which, in this case, are rollers (cylindrical rolling elements) 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 (cages) to ensure proper spacing and orientation.
