Needle roller bearings are equipped with thin and long rollers (the length of the roller is 3-10 times the diameter, and the diameter is generally not greater than 5mm), so the radial structure is compact, and its inner diameter and load capacity are the same as other types of bearings. The smallest diameter, especially suitable for supporting structures with limited radial installation dimensions. Needle roller bearings are used in different occasions, and the machining accuracy and surface quality should be combined with the bearing ring and purpose. The needle roller bearing is a bearing unit composed of a radial needle roller bearing and a thrust bearing component.

Needle bearings are roller bearings with cylindrical rollers. The rollers are thin and long relative to their diameter. This kind of roller is called a needle roller. Despite having a small cross-section, the bearing still has a high load bearing capacity, needle roller bearings are equipped with thin and long rollers (roller diameter D≤5mm, L/D≥2.5, L is the length of the roller), so The radial structure is compact, and its inner diameter and load capacity are the same as other types of bearings, and the outer diameter is the smallest. It is especially suitable for supporting structures with restricted radial installation dimensions.
