RNAO 50X65X20 Needle Roller Bearing 50x65x20mm
Specifications
Details
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. Single-row variants without an inner ring work well in compact setups with hardened shaft raceways. Bearings without flanges on the outer ring are separable, which means that the outer ring and the needle roller and cage assembly can be mounted separately.
