Needle roller bearings

Needle roller bearings are a type of bearing with elongated needle rollers as rolling elements. They typically consist of inner and outer rings, needle rollers, and a cage. Due to their smaller cross-sectional size, they are suitable for applications with limited space.

The longer and thinner shape of needle rollers allows these bearings to withstand larger radial loads under relatively small outer diameters. This feature makes needle roller bearings particularly useful in applications requiring high radial load capacity, such as automotive transmission systems, motorcycle engines, and other industrial machinery.

Needle roller bearings are suitable for high-speed rotation and applications with high precision requirements. They are widely used in aerospace devices, medical equipment, printing machinery, and various fields where a lightweight structure and high performance are essential.
