Needle rollers can be used to design full complement bearing arrangements for low-speed or oscillating applications. These compact bearing arrangements have a very high load carrying capacity when compared to bearings with a cage and are economical, provided the shaft and housing bore can serve as raceways raceways on shafts and in housings. They are made of carbon chromium steel, have a hardness of 58 to 65 HRC and have a precision ground surface.
