BEARING - NEEDLE (Doosan DWNI40016-FK000)

A damaged needle bearing can cause uneven rotation and premature wear in rotating assemblies. During inspection, a needle bearing may exhibit pitting or scoring that leads to increased friction and heat buildup. Keeping a needle bearing in sound condition helps maintain smooth shaft movement and reduces the risk of seizure. This aftermarket replacement part references Doosan as the OE maker and carries the cross-reference part number DWNI40016-FK000. The bearing type relies on cylindrical rollers to support radial loads with minimal clearance. A common failure consequence is that a worn needle bearing can produce noise and vibration, eventually locking the shaft. Verify the serial number or application, then call (562) 693-7748.
