Scope of application: the stamping outer ring needle roller bearing with cage is suitable for high speed and heavy load, and is mainly used in the transmission of machine tools, automobiles, motorcycles or textile machinery. Rammed ring needle roller bearings without cage are suitable for swinging working conditions under heavy loads because they are filled with needles. Such as the frame of an aircraft, the shaft end of the main wing of a missile, etc.

 

(2) Solid ring needle roller bearings of solid ring needle bearings, the commonly used solid ring needle bearings are NA type and RNA type.

 

Scope of application: solid ring needle roller bearings are mostly used in machine tools and automobile gearboxes. Their advantages are small radial section size and large radial load bearing. Standard solid ring needle roller bearings have cages, so the speed is higher, can meet the requirements of machine tools and auto transmissions.

 

(3) roller needle roller bearing

 

Scope of application: printing machinery, pasture machinery, agricultural machinery, CNC equipment guide roller, conveyor line, etc.

 

(4) Needle roller and cage assembly. The needle roller and cage assembly is actually a needle roller bearing without a ring

 

Scope of application: This kind of bearing is mainly used in the large and small end of the connecting rod of gearbox, motorcycle and automobile. As the temperature in the cylinder rises, the bearing is resistant to high temperature.
