BEARING - NEEDLE (Doosan DWA138660)

A damaged needle bearing can lead to uneven wear and premature failure of rotating components. During inspection, a needle bearing may exhibit pitting or scoring on its rollers, indicating contamination or inadequate lubrication. Needle bearings use small cylindrical rollers to reduce friction between moving surfaces while supporting radial loads. A failed needle bearing often causes increased vibration, noise, and eventual seizure of the shaft or housing. Keeping a needle bearing in sound condition helps maintain precise alignment and smooth rotation in mechanical assemblies. This aftermarket replacement part references Doosan part number DWA138660.
