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.
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
