Needle roller bering

Needle bearing is a kind of roller bearing with cylindrical roller. The roller is thin and long relative to its diameter. This roller is called a needle roller. Although it has a smaller section, the bearing still has a higher load bearing capacity. The needle roller bearing is equipped with thin and long rollers (roller diameter D ≤ 5mm, L / D ≥ 2.5, l is roller length). Therefore, the radial structure is compact. When its inner diameter and load capacity are the same as other types of bearings, the outer diameter is the smallest, especially suitable for the bearing structure with limited radial installation size.
