Needle roller bearings (needle bearing) is a cylindrical roller with roller bearings, relative to its diameter, roller both thin and long. This is called needle roller. Despite having a smaller cross-section, has a higher load bearing capacity, thin and long needle bearing mounted roller (roller diameter D≤5mm, L / D≥2.5, L is the length of the roller), so radial structure is compact, the diameter size and load capacity of the other types of bearings, minimum diameter, especially for limited radial dimensions of the support structure.With thin and long needle bearing roller (roller length of 3 to 10 times the diameter, the diameter of the generally small 5mm), so the radial structure is compact, its diameter size and load bearing capacity and other types are the same, the outer the minimum diameter, especially for radial mounting dimensions restricted support structure. needle roller bearings based on the use of different occasions, machining accuracy and surface quality should be bearing rings, use combinations. Needle roller bearings are bearing unit consists of radial and thrust needle roller bearings bearing component combinations.
