Brief introduction
Needle roller bearing, also known as needle bearing, is a kind of roller bearings with cylindrical rollers. Dependent on its diameter, the rollers, called needles, are thin and long. The radial structure is compact, the diameter size and load capacity are the same as other types of bearings with small outside diameter. In spite of cross section, they still have a high load carrying capacity, therefore, they are particularly suitable for limited radial space.
Types
1.Drawn cup needle bearing
2.Needle bearing with inner ring
3.Needle bearing without inner ring
4.Full complement needle bearing
5.Radial needle roller and cage assemblies
6.Thrust needle roller and cage assemblies
Typical applications
They are widely applied to motorcycles, mopeds, automotive, power tool, texitile machinery, printing machinery, food packing machinery, toys, etc.
Advantages
1.Good performance
2.High precision and durability
3.Good resistance ability
4.Low friction and high limiting rotation speed
5.Simple structure and easy to operate
