Manufacturers Supply Cylindrical Roller Bearing Sealed Needle Roller Bearings

Needle roller bearings (needle bearing) is a cylindrical roller with a roller bearing, 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), therefore radial structure is compact, its diameter size and load capacity and other types of bearings, minimum diameter, especially for radial mounting dimensions restricted support structure.

According to different occasions, can be used without inner ring of the bearing or needle roller and cage assembly, when the surface of the journal bearing surface and shell holes as bearing directly match the outer rolling surface, in order to ensure the load capacity and operating performance and have the same ring bearing, 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.

Application:
Needle roller bearings are widely used in cars, compressors, construction, electric motors, food industry, home appliances etc. As a rolling element, it turns the world.
