agricultural bearings needle roller bearings

Why do so many industries need to needle roller bearings?

Needle roller bearings are widely used at present market is very hot, and in this process, the field of machine tools use some relatively wide.

Scope of application: this agricultural bearings‍ bearing needle roller bearings are used for gearbox, motorcycle, automobile, the small end of connecting rod. Gear. Because the cylinder temperature reducer, increase, so the bearing high temperature. With thin and long needle bearing roller (roller length is 3~10 times the diameter, the diameter is generally not more than 5mm), so the radial structure is compact, its diameter size and load capacity compared with other types of bearings at the same time, minimum diameter, especially for radial installation support results in limited size. According to the use of different occasions, can be used without inner ring bearings or needle roller and cage assemblies, the Double Row Ball Slewing Bearing‍ shaft neck surface and the surface of shell holes matched with a bearing directly as bearing inner and outer rolling surface, to guarantee load capacity and operating performance and have the same ring bearing, shaft or housing holes raceway surface hardness, the machining precision and the surface quality of bearing ring raceway and similar.
