Needle Roller Bearing is a type of bearing with rolling elements, where the rolling elements are elongated cylindrical rollers, shaped like needles, hence the name. Compared to other types of roller bearings, needle roller bearings have longer rollers and smaller diameters. Their design enables these bearings to withstand large radial loads and work effectively in limited radial spaces.

Needle roller bearings are commonly used in automobile transmissions, connecting rod parts of engines, motorcycle engines, transmission systems of industrial machinery and equipment, etc. Due to their high efficiency, durability and compactness, they are widely used in many demanding applications.
