Needle roller bearings use needle rollers as their rolling elements rather than balls. The term "needle roller" usually means that its length is several times its diameter.

roller bearing needle have a smaller cross-sectional height and could keep the entire machine lighter and more compact, thus maintaining a relatively high load carrying capacity. The key components are the cage (also known as the separator or support) and the needle rollers.

Needle roller and cage assembly can be mounted directly as a stand-alone accessory, or cam roller bearings can be used in conjunction with other parts, inner and outer rings, to form complete needle roller bearings that can be used as stand-alone bearing support mounts.

Needle Roller Bearing Advantages
Needle roller bearings, developed by THB, as one of the most professional needle roller manufacturers in China, have the following advantages:

Because of the small radial cross section of needle roller bearings, they are very suitable for working conditions where the mounting space is small

Optimized needle roller and raceway shape design, so that the bearing has a higher radial load capacity
