Product Description

Product Description

NEEDLE ROLLER BEARING

Needle bearing is a roller bearing with cylindrical rollers. Compared with its diameter, the rollers are thin and long. This roller is called a needle roller. Although it has a small section, the bearing still has a high load-bearing capacity. The needle roller bearing has thin and long rollers (diameter D ≤ 5mm, L/D ≥ 2.5, L is the roller length), so the radial structure is compact. When its inner diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest, which is especially suitable for supporting structures with limited radial installation size.
