Combined bearing NKIA

Feature

    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, equipped with a thin and long needle bearing roller (roller diameter D≤5mm, L / D≥2.5, L is the length of the roller), so radial structure is compact, its diameter size and load capacity and other types of bearings, minimum diameter, especially for radial dimensions limited support structure.                

     Depending on different occasions, can be used without an inner ring of the bearing or needle roller and cage assemblies, then journal surface and the surface of the bearing shell hole to match directly as the bearing, the outer rolling surface, in order to ensure the load capacity and operating performance and have the same bearing rings, shaft or housing bore raceway surface hardness, machining accuracy and surface quality should be similar roller bearing rings. Such bearings can only bear radial load.
