What are needle roller bearings used for?

According to different occasions, needle roller bearings are equipped with long and thin rollers (roller diameter D≤5mm, L/D≥2.5, L is the length of the roller), so the radial structure is compact, the inside diameter size and load capacity of the same with other types of bearings, the outer diameter is the smallest, especially suitable for the radial installation size of the limited supporting structure.

Where can a ball bearing be applied?

As mentioned before, ball bearing can be applied in many fields. There is no exaggeration that needle roller bearing can be seen everywhere. Take cars for example, the wheels of automobiles require ball bearings. In addition to this, needle roller bearings are also used in a variety of entertainment equipment such as toys, watches, electronics, audio, and video. needle roller bearings are multi-functional materials with high wear resistance, and factories have high demands on bearing materials.

Before purchasing a ball bearing, please notice its sizes and manufactured materials. In general, large-scale needle roller bearing manufacturers are more reliable.
