A needle roller bearing is a type of roller bearing that uses long, thin cylindrical rollers (needles) to provide support and reduce friction between moving parts. These bearings are designed for high load-bearing applications while maintaining a compact size. The rollers are typically much longer than their diameter, which allows for a greater surface area contact between the rollers and the bearing raceways.
