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.

What’s the definition of a neddel roller bearing?

 

Needle bearing (needle bearing) is a roller bearing with cylindrical roller, relative to its diameter, the roller is thin and long.This type of roller is called a needle roller.Although has a small cross-section, bearing still has high load capacity, needle bearing with fine and long roller (roller diameter D 5 mm or less, acuity 2.5 L/D, L) for the roller length, so the radial structure is compact, its diameter and load capacity at the same time, with other types of bearing outside diameter to a minimum, especially suitable for the limited size of the radial installation supporting structure.

 (2)needle roller bearings with inner ring

 (3)  needle roller bearings with and without inner ring/needle roller bearings without inner ring and cage 

 (4) needle roller bearings with and without cage filled needle roller bearings 

 (5)open stamped outer ring needle roller bearings

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.
