Quantity:


Needle Roller Bearings have long, thin cylindrical rollers resembling needles. They excel at handling high radial loads in tight spaces, making them ideal for automotive transmissions, gearboxes, and machinery. Lightweight, cost-effective, and suitable for high speeds, they distribute loads evenly and require proper lubrication for durability. The outer ring includes two non-separable closure rings that act as flanges to guide the bearing axially.
