Stamping outer ring needle roller bearings have various structure types, and their application ranges are also different. Generally speaking, stamping outer ring needle roller bearings have different perforation and sealing types. Stamping outer ring needle roller bearings have no inner ring and contact with the surface directly, so that the processing accuracy and heat treatment hardness of bearings should be the same.

This kind of bearing is suitable for high-speed, heavy-duty, machine tools, automobiless, motorcycles gearbox or textile machinery. There is no retained stamping needle roller bearing ring frame; for example, full needle roller, suitable for heavy-duty working conditions, can be used as the plane frame of the shaft, wing end, etc.

The solid ring needle roller bearings are Na type and RNA type, which are mostly used in machine tools and automotive gearboxes. Its advantage is that the radial load of the radial bearing has a small cross-section size. Standard solid ring needle roller bearing seat, so high speed, to meet the requirements of machine tools, automotive gearbox.

Needle roller and cage components are actually needle roller bearings without inner rings. These bearings can be used in gearboxes, motorcycles, automobiless and other equipment with large and small connecting rods. Because of the increase of cylinder temperature, the bearing temperature is high, but needle roller bearings without inner rings can still maintain good stability.

Generally speaking, needle roller bearings have a wide range of applications, such as printing machinery, pasture machinery, agricultural machinery, roller CNC equipment track, conveyor line and other fields, and show excellent use effect to ensure the good operation of the equipment.
