Also available are needle roller and cage assemblies using molded, one-piece glass-reinforced engineered polymer cages. Needle rollers are equally spaced by means of a cage whose web section separates the rollers and provides guidance to keep them tracking in an orbital path. They feature a great many small diameter cylindrical rollers within each bearing and this ensures a large area remains in contact with the rotating surfaces, which is how they are able to handle heavier loads. Drawn cup needle roller bearings are available in open ends or single, closed-end designs. They are compact and offer large load capacity and high limiting speed. In general, these are unitized bearings consisting of the thrust needle roller and cage assembly and two special thrust washers used as raceways.
