Cage needle bearings consist of cylindrical needle rollers assembled into a cage or retainer.  The cage/retainer may be molded plastic.  Common materials include polyamide (nylon), acetal (delrin) or other engineered plastics.  Alternately, the cage/retainer may be made from low carbon steel via metal stamping and forming processes.  Sometimes the cage/retainer is machined.  Other materials include brass or stainless steel.  Needle rollers are most commonly manufactured from bearing grade chrome steel (52100 / GCr15).  This material is widely specified due to its high strength, hardness and wear resistance.
