Needle bearings are usually lubricated with grease, but oil or oil-mist lubrication is preferred for heavy-duty or high-speed applications. A needle roller bearing is a bearing that uses small cylindrical rollers. These rollers are used to reduce friction of a rotating surface. Can be combined with washers, make objects rotating smooth! Can serve as raceways between the faces of adjacent machine components. Can be used as inner or outer raceways
